Midrash su Salmi 61:3

Thereupon Noah cursed his seed, saying: Cursed be Canaan (Gen. 9:25). Because Ham had glanced at his naked father, his eyes became red. Because he related (what he had seen) to others with his mouth, his lips became twisted. Because he turned his face away (ignored his father’s condition), the hair of his head and beard was singed. And because he neglected to cover his naked father, he went about naked, with his prepuce extended. This happened to him because the Holy One, blessed be He, exacts retribution measure for measure. Nevertheless, the Holy One, blessed be He, relented and had mercy upon him, for His tender mercies are over all His works (Ps. 145:9). The Holy One, blessed be He, said: Inasmuch as he caused himself to be sold into slavery,²⁰His penalty for his actions: A servant of servants shall he be to his brothers (Gen. 9:25). let him go free because of the eye that sees and the mouth that speaks. Hence, the law states: A slave must be freed because of the loss of a tooth or an eye, as it is written: And if a man smite the eye of his bondman, or the eye of his bondwoman, and destroy it, he shall let him go free for his eye’s sake. And if he smite out his bondman’s tooth, or his bondwoman’s tooth, he shall let him go free for his tooth’s sake (Exod. 21:26–27). May we not logically conclude a fortiori:²¹That is, kal va-homer (a conclusion drawn from a minor to a major), one of the hermeneutical rules for expounding the Written Law. If a servant, purchased with money, must be released from bondage if his master blinds him or knocks out his tooth, should not the seed blessed of the Lord (Isa. 65:23), the planting of the Lord that He might be glorified (Ps. 61:3), be freed after their deaths from their sins? Hence, free among the dead (Ps. 88:6), indicating that they should go free (from sin) with all their two hundred and forty-eight limbs.

“…when my heart becomes faint…” (Psalms 61:3) Unto what point must one stand in prayer? R’ Yehudah says: until his heart becomes faint, as it says “A prayer for a poor man when he faints and pours out his speech before the Lord.” (Psalms 102:1) This is ‘when my heart becomes faint’.

“…on the rock that is higher than I…” (Psalms 61:3) Which is this? This is Jerusalem, as it says “And it became wider and it wound higher…” (Ezekiel 41:7) Therefore ‘on the rock that is higher than I.’ Knesset Yisrael said before the Holy One: Master of the World! I do not want to dwell with the enemy, but rather “I shall dwell in Your tent to eternity…” (Psalms 61:5) And so it says “O Lord, I love the dwelling of Your house and the place of the residence of Your glory.” (Psalms 26:8) So too it says “For a day in Your courts is better than a thousand; I chose to sit on the threshold of the house of My God rather than dwell in tents of wickedness.” (Psalms 84:11)
