"Luli toratecha she'asui v'goh...". Israel said: "If not for Your Torah that was with me and was my delight, then I would have been lost in my affliction." Similarly, Moses says in Psalm 94: "In the multitude of my anxieties within me, Your comforts delight my soul." And Pharaoh says in Exodus 5: "Let the work be heavier on the men."
They had books and would amuse themselves with them from Sabbath to Sabbath. Therefore it is said: "Your Torah is my delight forever; I will not forget Your precepts." They are life to Israel; if not for them, there would be no life. As it is written in Deuteronomy 30:20: "For He is your life and the length of your days."
And it is written in Proverbs 8:35: "For whoever finds me finds life." And it is written in Proverbs 9:11: "For by me your days will be multiplied, and years of life will be added to you." Israel said to God: "It is possible for a heifer to plow in two furrows. Why then did You say: 'For they are My servants, whom I brought out of the land of Egypt'?"
To which God responds: "I will save you from the oppressor." As it is written in Psalm 116: "Redeem me from the oppression of man." Therefore it is said: "Save me, and I will be saved."
