מדרש אויף ישעיהו 48:9

“The Kehatite,” that is what is written: “For My name's sake, I will defer My wrath and for My praise, I will exercise forbearance with you, so as not to eradicate you” (Isaiah 48:9). It is speaking of Israel. “For My name's sake, I will defer My wrath,” this is Israel, upon whom the Holy One blessed be He designated His name: “I am the Lord your God” (Exodus 20:2). And He joined His name¹⁰El. with their name, Israel. That is why He deferred His wrath against Israel, that He did not eliminate them, but rather, He collected from them¹¹He punished them. little by little in exile in order to absolve them. He did not seek to eradicate them, so his name would not be desecrated because of them. As we find when Israel was in Egypt, they rebelled against the Holy One blessed be He and the Holy One blessed be He wished to eliminate them, but He deferred His wrath with them for His name’s sake and did not do so, just as it says: “I said to pour My fury upon them, to spend My wrath upon them within the land of Egypt. But I acted for My name’s sake, so that it would not be profaned before the eyes of the nations” (Ezekiel 20:8–9). Likewise, when Israel departed, in the wilderness they rebelled against Him, and the Holy One blessed be He sought to eradicate them but He deferred His wrath with them for His name’s sake, as it is stated: “I said to pour My fury upon them [in the wilderness to eradicate them. But I acted for My name’s sake, so that it would not be profaned before the eyes of the nations…]” (Ezekiel 20:13–14). Likewise, the generation of the wilderness rebelled against the Holy One blessed be He and He sought to eradicate them, but He deferred His wrath with them for His name’s sake, and He took an oath that He would exact retribution against them with the servitude of the kingdoms, but he did not effect eradication, as it is stated: “I said I would pour My fury [upon them…in the wilderness]. But I restrained My hand, [and I acted for the sake of My name, that it not be profaned]” (Ezekiel 20:21–22). “I also raised My hand [to them in the wilderness, to disperse them among the nations and to scatter them through the lands]” (Ezekiel 20:23). “For My praise, I will exercise forbearance with you” (Isaiah 48:9), so that the name of the Holy One blessed be He will not be profaned through them; He will bring them the sealed redemption, as it is stated: “I will sanctify My great name that was profaned among the nations… I will take you from the nations…[and I will bring you to your land]” (Ezekiel 36:23–24).
Another matter, “I will exercise forbearance [oḥotam] with you” (Isaiah 48:9), because Israel was created to recite the praise of the Holy One blessed be He, just as it says: “This people, I formed for Myself; [they will recite My praise]” (Isaiah 43:21). For that purpose, so that His name would be praised in their midst, the Holy One blessed be He seals it [ḥotma] for good. Just as it says: “Place me as a seal [hotam] upon your heart, as a seal upon your arm” (Song of Songs 8:6). That caused them not to be eliminated in exile. That is, “so as not to eradicate you.”
Another matter, “for My name's sake, I will defer My wrath” (Isaiah 48:9), it is speaking of the Kehatites [hakehati]. To what is the matter comparable? It is to a king who had a son who joined robbers. They were apprehended and his son was apprehended with them. The king said: ‘What shall I do? Shall I execute the robbers? That is impossible, as my son is with them. For the sake of my son, I will free them now.’ So, the Levites were the bearers of the Tabernacle. The Holy One blessed be He was looking at Koraḥ and his congregation, who were destined to dispute with Moses and Aaron. The Holy One blessed be He said: ‘What shall I do to these? To kill them now is impossible, as they are intermingled with the other righteous ones.’ So as not to harm all of them with the attribute of justice, the Holy One blessed be He took half His name, and added ya [yod heh] to it [the word kehat], the Holy One blessed be He rendered it hakehati, heh at the beginning and yod at the end, that is ya, in order to provide them with protection until their day would come. That is, “for My name's sake, I will defer My wrath…” That is why hakehati is written here.

(Numb. 4:18:) “Do not cut off.” This text is related (to Ps. 33:18), “Behold, the eye of the Lord is on those who fear Him….” The text speaks along many lines of thought.¹²¹Shittim. For this use of the word, Buber, n. 209, cites Lev. R. 34:8. For the other interpretations, see above, Gen. 6:5. For what we need, however, it is speaking about the tribe of Levi.¹²²Numb. R. 5:1. And where is it shown? Where the tribe of Levi is called those who fear the Lord, as stated (in Mal. 2:5), “and I gave them (i.e., life and peace) as well as fear, and he feared Me.” (Ps. 33:19) “On those who wait for His steadfast love,” because they are always waiting for the name of the Holy One, blessed be He. (Ps. 33:19:) “To deliver their soul from death and to keep them alive in famine,” through the twenty-four gifts which the Holy One, blessed be He, has given them.¹²³THal. 2:7-9; BQ 110b (bar.); Hul. 133b (bar.); cf. Hal. 4:9. These are them: ten in the sanctuary, ten within the borders, and four in Jerusalem. The ten in the sanctuary: the sin offering (Lev. 6:17-23; Zev. 5:3), the guilt offering (Lev. 5:14-16, 20-26; 19:20-22; Zev. 5:5), the peace sacrifices and the community peace sacrifices (Lev. 23:19-20; Zev. 5:5), the sin offering of a fowl (Lev. 5:8), the guilt offering for a doubtful sin (Lev. 5:17-19; Zev. 5:5), the leper's log of oil (Lev. 14:12), the two loaves (Lev. 23:17), the shewbread (Exod. 25:30; Lev. 24:5-9), the remnant of the omer (Lev. 23:10-12; Men. 10:4), and the remainder of the meal offering (Lev. 2:3).
The ten within the borders: the terumah (Numb. 18:12), the terumah of the tithe (Numb. 18:25-29), the hallah (Numb. 15:18-21), the first of the shorn wool (Deut. 18:4), the shoulder, the cheeks, and the stomach (Deut. 18:3), the redemption of the [first-born] son (Numb. 18:15-16), [the redemption of] a firstling ass (Exod. 13:13), [the payment for] the robbery of a proselyte (Thal. 2:9; Bq 110b; Hul. 133b), things consecrated (Numb. 18:14; Bik. 3:12), and a field of possession (Lev. 27:16-21)
The four in Jerusalem: the firstlings [of animals] (Numb. 18:17-18), the first fruits (Exod. 23:19; Numb. 18:13; Hal. 4:9), the priest's share from the thank-offering ram and from the nazarite ram, the breast of the peace offerings, and the thigh (Exod. 29:27-28; Lev. 7:12-14; 31-34; 10:14-15; Numb. 6:13-20; 18:18), and skins of [burnt, sin, and guilt] offerings (Lev. 7:8; Zev. 12:3)
Behold, these are twenty-four gifts. Ergo (in Ps. 33:19), “and to keep them alive in famine. (Numb. 4:18) “Do not cut off [the tribe of the Kohathite families from the Levites].” The Holy One, blessed be He, foresaw that Korah was going to arise and disagree about the priesthood.¹²⁴Cf. Numb. R. 5:5. The Holy One, blessed be He, said. “I will not destroy the Levites because of Korah.” (Numb. 4:18:) “Do not cut off [the tribe of the Kohathite families from the Levites].” This text is related (to Is. 48:9), “For the sake of My name I will delay My anger, and for My praise I will hold back for you so as not to cut you off.” To what is the matter comparable?¹²⁵Numb. R. 5:6. To a king who had a son that was associated with bandits;¹²⁶Gk.: lestai. and when they were captured, his son was captured with them. The king said, “What shall I do? Shall I execute the robbers? Possibly my son is with them. Instead, for the sake of my son, I will exonerate them for now.” Similarly, the Levites carried the tabernacle. Thus it is stated (in Numb. 7:9), “But to the Children of Kohath he gave no [wagons], because they had the service of the holy.” When the Holy One, blessed be He, saw that Korah and his assembly were going to be opposed to Moses and Aaron, the Holy One, blessed be He, said, “What shall I do with these? To kill them in the desert is not possible.” Why? Because the Holy One, blessed be He, had taken half of His name and bestowed it upon them, the yh (of yhwh) in the Kohathite (hqhty in Numb. 4:18).¹²⁷Numb. R. 5:6, and Yalqut Shim‘oni, Is. 48:9, 326 (466) add that the letters from the divine name appear at the end and the beginning of HQHTY, and Numb. R. explains further that the Holy One added the definite article (H) to the name, Kohathite, for this very reason. It therefore says (in Is. 48:9), “For the sake of My name I will delay¹²⁸Literally: LENGTHEN. This verb may have suggested that the Holy One deliberately lengthened the name, Kohathite, with the addition of the article. My anger….”

[Another interpretation] (of Numb. 4:18:) DO NOT CUT OFF THE TRIBE OF THE KOHATHITE FAMILIES <FROM THE LEVITES>. The Holy One foresaw that Korah was going to arise and be opposed to the priesthood.¹⁴⁸Cf. Numb. R. 5:5. The Holy One said: We will not destroy the Levites because of Korah. (Numb. 4:18:) DO NOT CUT OFF <THE TRIBE OF THE KOHATHITE FAMILIES FROM THE LEVITES>. This text is related (to Is. 48:9): FOR THE SAKE OF MY NAME I WILL DELAY MY ANGER, AND FOR MY PRAISE I WILL HOLD BACK FOR YOU SO AS NOT TO CUT YOU OFF. To what is the matter comparable?¹⁴⁹Numb. R. 5:6. To a king who had a son that was associated with bandits;¹⁵⁰Gk.: lestai. and when they were captured, his son was captured with them. The king said: What shall I do? Shall I execute the robbers? Possibly my son is with them. Instead, for the sake of my son, I will free them for now. Similarly, the Levites carried the Tabernacle. Thus it is stated (in Numb. 7:9): [BUT TO THE CHILDREN OF] KOHATH HE GAVE NO <WAGONS>, [BECAUSE THEY HAD THE SERVICE OF THE HOLY OBJECTS, WHICH THEY CARRIED ON THE SHOULDER], When the Holy One saw that Korah and his assembly were going to be opposed to Moses and Aaron, the Holy One said: What shall I do with these? To kill them is not possible. Why? Because the Holy One had taken half of his name and bestowed it upon them, the YH (of YHWH) in THE KOHATHITE (HQHTY in Numb. 4:18).¹⁵¹Numb. R. 5:6, and Yalqut Shim‘oni, Is. 48:9, 326 (466) add that the letters from the divine name appear at the end and the beginning of HQHTY, and Numb. R. explains further that the Holy One added the definite article (H) to the name, Kohathite, for this very reason. It therefore says (in Is. 48:9): FOR THE SAKE OF MY NAME I WILL DELAY¹⁵²Literally: LENGTHEN. This verb may have suggested that the Holy One deliberately lengthened the name, Kohathite, with the addition of the article. MY ANGER, <AND FOR MY PRAISE I WILL HOLD BACK FOR YOU> SO AS NOT TO CUT YOU OFF.
