New American Standard Bible (NASB)
Hebrews 6
17 In the same way God, desiring even more to show to the heirs of the promise the unchangeableness of His purpose, interposed with an oath,
18 so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us.
19 This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the veil,
20 where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek.
Hebrews 7
1 For this Melchizedek, king of Salem, priest of the Most High God, who met Abraham as he was returning from the slaughter of the kings and blessed him,
2 to whom also Abraham apportioned a tenth part of all the spoils, was first of all, by the translation of his name, king of righteousness, and then also king of Salem, which is king of peace.
3 Without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, he remains a priest perpetually.
4 Now observe how great this man was to whom Abraham, the patriarch, gave a tenth of the choicest spoils.
5 And those indeed of the sons of Levi who receive the priest’s office have commandment in the Law to collect a tenth from the people, that is, from their brethren, although these are descended from Abraham.
6 But the one whose genealogy is not traced from them collected a tenth from Abraham and blessed the one who had the promises.
7 But without any dispute the lesser is blessed by the greater.
