Did God make one or three or perhaps even more covenants with Abraham? Do Genesis 12, Genesis 15, Genesis 17, and Genesis 22 refer to different covenants? This article argues that the Lord made a single covenant with Abraham and later supplemented that covenant by adding name changes, requirements, and promises.
This article concerns the covenant that God makes with Abraham after he returned from defeating the the kings of the east. It is an account that continued to unfold how the seed of the woman will triumph over the seed of the serpent. In Genesis 15, God strengthens the promise of this seed, although there is nothing yet to prove that the seed will come. The only thing Abraham holds on to is the promise of God.
The author goes through the life of Abraham, in order to demonstrate how his faith in God is an example for those who believe today. Those who believe will take hold of the promises by faith and also get to receive the title of being Abraham's children, even though they have not obeyed the Law of Moses, and have sinned against God.
Beale notes the cultic affinities drawn between the garden of Eden and the temple of Israel. The word pair usually translated as "cultivate" (['abad]) and "keep" ([shamar]) occur together in the Old Testament elsewhere referring only either to Israelites "serving" God and "guarding" (keeping) God's Word, or to priests who "keep" the "service" (or "charge") of the tabernacle.
