The focus of this chapter is the covenant of circumcision.
But what jumped out at me, were the names.
Abram to Abraham.
Sarai to Sarah.
The name of the unborn Isaac, to remind Abraham that he laughed at God’s promise.
And my favorite of all, El Shaddai. Our English Bibles translate this, “God almighty,” but it is the name God gives to Himself,
“I am El Shaddai”
El is the term for God and Shaddai is often viewed as a translation for all powerful —
but there is also “the suggestion that Shaddai is a composite term of sha (“the one who”) and dai (“is sufficient”). The later Greek versions have adopted this meaning.”Van Groningen, G. (1988). God, Names Of. In Baker encyclopedia of the Bible (Vol. 1, p. 882). Grand Rapids, MI: Baker Book House.
Sarai and Abram who could not have children, became,
Sarah and Abraham because God is sufficient to make a great nation out of the infertile–where there is nothing, God is sufficient to make something.
