13When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself, 14saying, “I will surely bless you and give you many descendants.” 15And so after waiting patiently, Abraham received what was promised.
16Men swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument. 17Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. 18God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope offered to us may be greatly encouraged. 19We have this hope as an anchor for the soul, firm and secure.
