Hebrews 6:19-20J.B. Phillips New Testament (PHILLIPS)
16-20 Among men it is customary to swear by something greater than themselves. And if a statement is confirmed by an oath, that is the end of all quibbling. So in this matter, God, wishing to show beyond doubt that his plan was unchangeable, confirmed it with an oath. So that by two utterly immutable things, the word of God and the oath of God, who cannot lie, we who are refugees from this dying world might have a source of strength, and might grasp the hope that he holds out to us. This hope we hold as the utterly reliable anchor for our souls, fixed in the very certainty of God himself in Heaven, where Jesus has already entered on our behalf, having become, as we have seen, “High Priest for ever after the order of Melchizedek”.
