15 And so, after he had patiently endured, he obtained the promise.
16 For men verily swear by the greater; and an oath for confirmation is to them an end of all strife.
17 Wherein God, willing more abundantly to show unto the heirs of promise the immutability of his counsel, confirmed it by an oath;
18 That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us;
19 Which hope we have as an anchor of the soul, both sure and steadfast, and which entereth into that within the veil;
20 Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchizedek.
Hebrews 7 Intro: Of the Melchizedek and Aaronic priesthood.
1 For this Melchizedek, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;
2 To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;
3 For this Melchizedek was ordained a priest after the order of the Son of God, which order was without father, without mother, without descent, having neither beginning of days, nor end of life. And all those who are ordained unto this priesthood are made like unto the Son of God, abiding a priest continually.
4 Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.
