(Gen. 17:1, cont.:) AND HE SAID UNTO HIM: I AM GOD ALMIGHTY ('L ShDY).¹⁰⁹ to mean GOD WHO IS ENOUGH. Enough (DY) of foreskin! Up to now foreskin has been customary, but circumcision has been concealed. It is enough (DY) for the world that I am his God.

footnotes: ¹⁰⁹ The midrash understands ’L ShDY

Another interpretation (of Gen. 17:1): I AM GOD ALMIGHTY ('L ShDY). R. Abbahu said: When the Holy One created his world, he created the heavens and the earth.¹¹⁰. 12a; Gen. R. 46:3; PRE 3; above, 1:11; below, 10:12, 16. Then he told them that they should continue to spread out, as stated (in Is. 40:22): WHO HAS STRETCHED OUT THE HEAVENS LIKE A CURTAIN AND SPREAD THEM OUT LIKE A TENT TO DWELL IN. If he had not said: Enough! to them, they would have continued to be spread out until the dead rise (at the end of time). What the Holy One said to Abraham was : I am the one who said to my world: Enough (DY)! So also he says to foreskin: Enough!

(Gen. 17:1, cont.:) WALK BEFORE ME AND BE PERFECT . Before he performed circumcision, the Holy One never said: WALK BEFORE ME. Why? Because he was uncircumcised. After he performed circumcision, the Holy One said: WALK BEFORE ME. Before he performed circumcision, he was not whole. After he performed circumcision, he became whole.
