You will find this agreement (also called a covenant) principally at Genesis 22:15-18 (although there are several other references throughout Genesis about this pact between God and Abraham):
And Jehovah's angel proceeded to call to Abraham the second time out of the heavens 16 and to say: "'By myself I do swear,' is the utterance of Jehovah, 'that by reason of the fact that you have done this thing and you have not withheld your son, your only one, 17 I shall surely bless you and I shall surely multiply your seed like the stars of the heavens and like the grains of sand that are on the seashore; and your seed will take possession of the gate of his enemies. 18 And by means of your seed all nations of the earth will certainly bless themselves due to the fact that you have listened to my voice.'"
There are a series of divine covenants in The Bible, and this is a great one to study because it will end up affecting all humankind, "all the nations of the earth."
This Abrahamic Covenant is related to the covenant God made in Genesis 3:15 in the Garden of Eden, when He made an agreement to bring forth a Seed, or offspring, who would undo all the damage done by Satan the Devil, who is referred to as "the original serpent" in Revelation 12:9 (see also Romans 16:20 and 1 John 3:8). For Christians, the primary Seed is Jesus Christ, who came through the family line of Abraham. The blessings that result from the Abrahamic Covenant include the possibility of enjoying friendship with God as was the case with Abraham (James 2:23) and the restoration of Paradise (Psalm 37:29; Luke 23:43).
The agreement between God and Abraham was called a covenant.

The Abrahamic Covenant.
I believe this is the convenant that God made with Abraham to make of Abraham's family a great nation.
It is called the "Covenant"-- the promise Abraham made with God, and God made with Abraham.

An agreement with God is usually called a covenant.
The agreement that God made with man is known as a covenant. In Christianity, one of the key covenants is the covenant between God and the Israelites, as outlined in the Old Testament. In Christianity, the New Covenant is believed to have been established through the life, death, and resurrection of Jesus Christ.
"Here I am."
Abraham
God called Abraham righteous because of his faith and obedience. Abraham trusted in God's promises, demonstrated by his willingness to leave his homeland and obey God's commands, such as when he was prepared to sacrifice his son Isaac. This faith and obedience showed Abraham's righteousness before God.
The spread in belief of one God is called monotheism. This was made possible by Abraham.
God would bless Abraham and his descendants.
God, Abraham and Moses are all still called by their names. Only Jacob's name was changed and he is now called Israel.
