5 Now the law requires the descendants of Levi who become priests to collect a tenth from the people-that is, from their fellow Israelites-even though they also are descended from Abraham.
5 And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:
5 And those descendants of Levi who receive the priestly office have a commandment in the law to take tithes from the people, that is, from their brothers,
5 Priests descended from Levi are commanded by law to collect tithes from the people, even though they are all more or less equals, priests and people, having a common father in Abraham.
5 And indeed those who are of the sons of Levi, who receive the priesthood, have a commandment to receive tithes from the people according to the law, that is, from their brethren, though they have come from the loins of Abraham;
5 Now the law of Moses required that the priests, who are descendants of Levi, must collect a tithe from the rest of the people of Israel, who are also descendants of Abraham.
Matthew Henry's Commentary on Hebrews 7:5
Commentary on Hebrews 7:4-10
(Read Hebrews 7:4-10)
That High Priest who should afterward appear, of whom Melchizedec was a type, must be much superior to the Levitical priests. Observe Abraham's great dignity and happiness; that he had the promises. That man is rich and happy indeed, who has the promises, both of the life that now is, and of that which is to come. This honour have all those who receive the Lord Jesus. Let us go forth in our spiritual conflicts, trusting in his word and strength, ascribing our victories to his grace, and desiring to be met and blessed by him in all our ways.
