Comentario citado sobre Malaquías 3:20

And he was sitting at the entrance of the tent in the heat of the day. This verse teaches that from two aspects Abraham was worthy of seeing the Divine Presence. The first is that he sat at the entrance of the tent to see if guests would come, and through the merit of charity a person merits to see the Divine Presence, as it is said As for me, through righteousness I shall behold Your face (Psalms 17:15). This explains the use of the letter kaf in kechom hayom [like the heat of the day] — for it should have said bechom hayom [in the heat of the day]. Rather, he acted like the heat of the sun which waits to do righteousness, as it is said sun of righteousness with healing in its wings (Malachi 3:20). For through God’s kindness the sun shines, as it is written To Him Who makes the great lights, for His kindness endures forever (Psalms 136:7). The second aspect is that he sat in the heat of the day seeking the healing sun with its wings; therefore it was fitting that God’s glory would be revealed to him to visit the sick.

והוא יושב פתח האהל כחם היום, “and he was seated at the entrance to the tent as the day grew hot.” The plain meaning of these words is that seeing Avraham was weakened by the circumcision he took advantage of the heat of the sun to act as therapy for his wounds. This is why he was outside at a time when normal healthy people stay inside to take advantage of the shade. The basis for the sun providing therapy is derived from Maleachi 3,20 כי השמש מרפא בכנפיה, “for the sun brings healing on its wings.”

The law of the Lord is perfect That too illuminates like the sun, as is written at the end of the topic: “enlightening the eyes,” and Scripture states (in Prov. 6:23): “For a commandment is a candle and the Torah is light.” Another explanation: and none is hidden from its heat on the Day of Judgment, [as is stated in Malachi 3:19]: “And the sun that comes shall burn them up.” But the law of the Lord is perfect; it restores the soul to ways of life and it protects those who study it from that burning, as is stated (ibid. verse 20): “And the sun of mercy shall rise with healing...for you who fear My Name.”

and behold, etc. Some things adopt both masculine and feminine gender, such as (Gen. 19:23): “The sun had risen (יָצָא) [msc.] over the earth, etc.”; (Mal. 3:20), “And for you who fear My name, shall the sun of mercy rise (וְזָרְחָה) [fem.]), etc.” [Likewise] (Gen. 32:9), “If Esau comes to the one camp (הָאַחַת) [fem.] and strikes it (וְהִכָּהוּ) [msc.].

of the...multiplicity Heb. בפש, an expression of multiplicity, like (Malachi 3:20), “and be fat (ופשתם),” and like (Jer. 50:11), “as you become fat (תפושו)”; (Lev. 13:51), “that the mark has spread (פשה).”

ויזרח לו השמש AND THE SUN SHONE UPON HIM— This is the expression that people use: “When we reached such-and-such a place the dawn broke upon us”. This is its literal sense. But the Midrash says that לו means, “for his needs” — to heal his lameness. Thus, too, you read in Scripture a similar metaphor (Malachi 3:20) “the sun of righteousness with healing in its wings”. The hours that it had set before its time for his sake when he left Beer-Sheba (cp. Genesis 18:11) it now rose before its time for his sake (Sanhedrin 75b).
