Genesis 17:1-2

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].”
