Hebrews 6:17-20

¹⁷Wherein God, being determined to show more abundantly to the heirs of the promise the immutability of his counsel, interposed with an oath; ¹⁸that 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 take hold of the hope set before us, ¹⁹which we have as an anchor of the soul, a hope both sure and steadfast and entering into that which is within the veil; ²⁰where as a forerunner Jesus entered for us, having become a high priest forever after the order of Melchizedek.
