God’s unchangeable promise

¹³ When God was making his promise to Abraham, you see, he had nobody else greater than himself by whom he could swear, and so he swore by himself, ¹⁴ with the words, “I will most surely bless you, and multiply you very greatly.” ¹⁵ And so in this way Abraham, after much patience, obtained the promise. ¹⁶ People regularly swear by someone greater than themselves, and in all their disputes the oath confirms the matter and brings it to closure. ¹⁷ So when God wanted to show all the more clearly to the heirs of the promise just how unchangeable his will was, he guaranteed it with an oath, ¹⁸ so that through two unchangeable things, in which it is impossible that God should tell a lie, those of us who have come for refuge should have solid encouragement to take hold of the hope which lies before us. ¹⁹ We have this hope like an anchor, secure, solid, and penetrating into the inner place behind the curtain, ²⁰ where Jesus has gone in ahead of us and on our behalf, having become a high priest forever according to the order of Melchizedek.
