“Isaac was overcome with great trembling, and he said: Who then is he who hunted game, and brought it me, and I ate from all before you came, and I blessed him? Indeed, he shall be blessed” (Genesis 27:33). “Isaac was overcome with great trembling.” It is written: “A man’s trembling sets a snare, and one who trusts the Lord will be exalted” (Proverbs 29:25) – the trembling that Ruth caused Boaz, as it is stated: “He trembled and recoiled” (Ruth 3:8), “sets a snare” – by right he should have cursed her.
However, “one who trusts the Lord will be exalted” – he considered it, and blessed her: “He said: May you be blessed to the Lord, my daughter” (Ruth 3:10). The trembling that Jacob caused Isaac, as it is stated: “Isaac was overcome with great trembling,” “sets a snare” – by right he should have cursed him. However, “one who trusts the Lord will be exalted” – he blessed him and said: “Indeed, he shall be blessed.”
