Genesis 17:1-9

When Abram was ninety-nine years old, the LORD appeared to him and said, “I am God Almighty; Walk [habitually] before Me [with integrity, knowing that you are always in My presence], and be blameless and complete [in obedience to Me]. “I will establish My covenant (everlasting promise) between Me and you, And I will multiply you exceedingly [through your descendants].” Then Abram fell on his face [in worship], and God spoke with him, saying, “As for Me, behold, My covenant is with you, And [as a result] you shall be the father of many nations. “No longer shall your name be Abram (exalted father), But your name shall be Abraham (father of a multitude); For I will make you the father of many nations. I will make you exceedingly fruitful, and I will make nations of you, and kings will come from you. I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you. [Gal 3:16] I will give to you and to your descendants after you the land in which you are a stranger [moving from place to place], all the land of Canaan, as an everlasting possession [of property]; and I will be their God.” [Acts 7:5] Further, God said to Abraham, “As for you [your part of the agreement], you shall keep and faithfully obey [the terms of] My covenant, you and your descendants after you throughout their generations.
