Genesis 15:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ But the word of the Lord came to him, ‘This man shall not be your heir; no one but your very own issue shall be your heir.’ ⁵ He brought him outside and said, ‘Look towards heaven and count the stars, if you are able to count them.’ Then he said to him, ‘So shall your descendants be.’ ⁶ And he believed the Lord; and the Lord^[a] reckoned it to him as righteousness.
