Then He brought him outside and said, “Look now toward heaven, and count the stars if you are able to number them.” And He said to him, “So shall your descendants be.” And he believed in the Lord, and He accounted it to him for righteousness. — Genesis 15: 5-6 NKJV.
“By Myself I have sworn, says the Lord, because you have done this thing, and have not withheld your son, your only son, blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore…” — Genesis 22:16-17 NKJV.
