Genesis 15:4-5

AKJV(i) 4 And, behold, the word of the LORD came to him, saying, This shall not be your heir; but he that shall come forth out of your own bowels shall be your heir. 5 And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if you be able to number them: and he said to him, So shall your seed be.
