מדרש אויף תהילים 41:10

There was one who used to say: "Happy is he who hears [himself abused] and minds it not; he will escape a hundred evils." Said R. Samuel to R. Juda: "This is written in the Scripture (Ps. 17, 14) As one letteth loose a stream of water so is the beginning of strife." There was another man who used to say: "A thief is not killed for stealing two or three times." And Samuel said to R. Juda: "This is also written in a passage (Am. 2, 5) Thus hath said the Lord, for three transgressions of Israel, and for four, will I not turn away their punishment." There was another man who used to say: "Seven pits are open for the righteous man [and he escapes]; but one for the evil doer into which he falls." Samuel said to R. Juda; "This also is written in a passage (Prov. 24, 16) For a righteous man falleth seven times, and riseth up again; but the wicked stumble under adversity." There was another man who used to say: "Let him whose cloak the court has taken away, sing a song and go on his way." Samuel said to R. Juda: "This is also written in the Scriptures (Ex. 18, 23) The whole of this people [including the loser] will come to its place in peace." There was another man who used to say: "When she slumbers, the basket [upon her head] drops — i.e., laziness begets ruin." Samuel again said to R. Juda: "This is written in the Scriptures (Ecc. 10, 18) Through slothful hands the rafters will sink," etc. There was another man who used to say: "The man on whom I relied lifted up his club and stood against me." Samuel said to R. Juda. "This is written in the following passage (Ps. 41, 10) Yea, even the man that should have sought my welfare, in whom I trusted, who eateth my bread, hath lifted up his heel against me."

Rabbi Yitzḥak said: To what is the matter comparable? To an akhina¹⁶A kind of poisonous snake. that was sitting at a crossroads and biting passersby. Along came a darvon¹⁷A kind of non-venomous snake. and sat next to it. A snake charmer came along and saw them. He said, ‘This akhina, it is its nature to bite. But this one, I am surprised that he has come and clung to it.’ So, too, Moses was saying: ‘Miriam, who spoke in that manner, that is the nature of women, they like to chatter. [But] the righteous Aaron, did he have to speak against me as well?’ Moses said: ‘“[Miriam spoke, and also Aaron]” (Numbers 12:1). That “Miriam spoke” [is understandable], but could it be “and also Aaron”?’ (Numbers 12:1). When Moses learned that Aaron also spoke [against him], he began crying out: “Even my ally, upon whom I relied, who partook of my bread, has lifted his heel against me”? (Psalms 41:10). What is “my ally [ish shlomi]”? This is Aaron, who bestows peace [shalom] upon me, as it is stated [in the priestly blessing]: “He will grant peace to you” (Numbers 6:26). “Upon whom I relied” – when he stopped the angel of death. From where is this known? It is as it is stated: “Aaron returned to Moses, to the entrance of the Tent of Meeting, and the plague was stopped” (Numbers 17:15). “Who partook of my bread” – these are the twenty-four priestly gifts that he receives as benefits from Israel.¹⁸Enumerated in Numbers chapter 18. After all this goodness, he “has lifted his heel against me.”
“Miriam spoke against Moses, and also Aaron” (Numbers 12:1) – Rabbi Levi said: There are four [negative] traits found in women: They are gluttons, eavesdroppers, jealous people, and lazy people. Gluttons – from where is it derived? It is from Eve, as it is written: “The woman saw that the tree was good for eating…” (Genesis 3:6). Eavesdroppers – from where is it derived? It is as it is written: “Sarah was listening at the entrance of the tent” (Genesis 18:10), as she was eavesdropping on the angel. Jealous people – from where is it derived? It is as it is written: “Rachel was jealous of her sister” (Genesis 30:1). Lazy people – from where is it derived? It is as it is written: “Hurry, three se’a of high quality flour” (Genesis 18:6).¹⁹Since Abraham had to hurry her on, the implication is that she was not acting with alacrity. The Rabbis said two more: They are sensitive and talkative. Sensitive – from where is it derived? “Sarai said to Abram: The injustice done to me is on you” (Genesis 16:5). Talkative – from where is it derived? It is as it is written: “Miriam spoke [against Moses].”
Another interpretation, “Miriam spoke” – Rabbi Yehoshua of Sikhnin said: When the Holy One blessed be He came to create Eve from Adam, He was contemplating [hitbonen] from where to create her, as it is stated: “The Lord God built [vayiven] the side…” (Genesis 2:22). The Holy One blessed be He said: ‘I will not create her from the eye, so she should not be curious; nor from the ear, so she should not be an eavesdropper; nor from the mouth, so she should not be a chatterer; nor from the hand, so she should not steal; nor from the foot, so she should not be one who walks about. From where will I create her? From a concealed limb of his, from the thigh.’ Nevertheless, it was to no avail, and all [these traits] that the Holy One blessed be He intended not to be in her, they are all found [even] in the most upright [among them]. The Holy One blessed be He had said: ‘I will not create her from the eye, so she should not be curious’ – Eve, it is written in her regard: “The woman saw….” ‘I will not create her from the ear, so she should not be an eavesdropper’ – “Sarah was listening ….” ‘I will not create her from the hand, so she should not steal’ – “Rachel stole the household idols” (Genesis 31:19). ‘I will not create her from the foot, so she should not be one who walks about’ – but Leah, it is written in her regard: “Leah went out to greet him…” (Genesis 30:16). ‘I will not create her from the mouth, so she should not be a chatterer’ – but the righteous Miriam, it is written in her regard: “Miriam spoke.” See what befell her: “Remember what the Lord your God did to Miriam.”

R. Jochanan said further: "At first David called Achitophel master, then he called him associate and finally he called him disciple. At first he called him master, (Ps. 55, 14) But it was thou, a man mine equal, my companion and my familiar friend; then he called him associate, (Ib.) We took sweet counsel together, etc.; and finally he called him disciple (Ib. 41, 10) Yea, mine own familiar friend, in whom I trusted, who did eat of my bread, etc.
