Jacob's Blessing El Shaddai as Enough to His Sufferings

Midrash Tanchuma Buber, Miketz 16:2

Another interpretation (of "And God Almighty"): Rabbi Alexandri said: Happy is the man upon whom sufferings come, and the Holy One, blessed be He, says to them, "Enough!"—for they have an end. Who was this? This was Jacob, who said to his sons, "And God Almighty (El Shaddai)"—may God (El) say to my sufferings, "Enough (dai) for you." Thus: "And God Almighty (El Shaddai)."
