Sure Promise of God

¹³ For when God made a promise to Abraham, because He could vow by no one greater, He vowed by Himself, ¹⁴ saying, “Surely I will bless you, and surely I will multiply you.”^{[a] 15} So after Abraham had patiently endured, he obtained the promise.

¹⁶ For men indeed swear by a greater authority than themselves, and for them an oath of confirmation ends all dispute. ¹⁷ So God, wanting to show more abundantly the immutability of His counsel to the heirs of promise, confirmed it by an oath. ¹⁸ So that by two immutable things, in which it was impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us. ¹⁹ We have this hope as a sure and steadfast anchor of the soul, which enters the Inner Place behind the veil. ²⁰ This is where Jesus has entered for us as a forerunner, since He has become the everlasting High Priest in the order of Melchizedek.
