Hebrews 6:18-20

that by two immutable things, in which it is impossible for God to lie, we may have a strong encouragement, who have fled for refuge to lay hold of the hope set before us: which we have as an anchor of the soul, a hope both sure and stedfast and entering into that which is within the veil; whither as a forerunner Jesus entered for us, having become a high priest for ever after the order of Melchizedek.
