Genesis 17:2 Meaning

1And when Abram was ninety years old and nine, the LORD appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect.

2And I will make my covenant between me and thee, and will multiply thee exceedingly.

3And Abram fell on his face: and God talked with him, saying,

4As for me, behold, my covenant is with thee, and thou shalt be a father of many nations.
