Genesis 15:5-6

And the LORD brought Abram outside [his tent into the night] and said, “Look now toward the heavens and count the stars—if you are able to count them.” Then He said to him, “So [numerous] shall your descendants be.” [Heb 11:12] Then Abram believed in (affirmed, trusted in, relied on, remained steadfast to) the LORD; and He counted (credited) it to him as righteousness (doing right in regard to God and man). [Rom 4:3, 18-22; Gal 3:6; James 2:23]
