Hebrews 7:20 says that Jesus was not made a priest without God’s solemn oath, and that this oath sets him apart from the Levitical priests who served before him. The verse is part of the writer’s argument that Jesus holds a priesthood that is greater, lasting, and guaranteed by God’s own word. The author of Hebrews is writing to Jewish Christians who knew the temple system well and needed to see how Jesus fulfills and surpasses it.

What Hebrews 7:20 Means
The phrase “inasmuch as” introduces a comparison. The writer is pointing out a difference between two groups of priests. The Levitical priests were appointed through the law of descent from Aaron, and God did not swear an oath to install them. Jesus, by contrast, was established as priest in a way that involved God speaking an oath about him. That oath is what makes his priesthood different in kind.
The verse does not say that oaths are the reason Jesus is a priest, as if God needed to be persuaded. It highlights how God chose to confirm his purpose. An oath in ancient usage was a way of binding one’s word with full seriousness, and the writer uses this to show that God’s commitment to Jesus’s priesthood is firm and unchangeable.
What the verse does not promise is a detailed description of how the oath was spoken or a technical theory of priesthood. Its aim is to assure readers that Jesus’s role rests on something far more secure than the inherited and temporary arrangement of the law.
The Context of Hebrews 7:20
Hebrews is a letter whose author is unnamed in the text. It was traditionally attributed to Paul in the early church, though most modern scholars do not hold that view. The audience was likely Jewish Christians facing pressure to return to the familiar temple worship and its sacrifices. The writer argues throughout that Jesus is superior to angels, to Moses, and to the old priesthood.
Verses 17 to 19 set up the contrast by quoting Psalm 110 and stating that an earlier commandment has been set aside because it was weak and could not make anything perfect. Verse 21 then explains the oath in more detail, and verse 22 says Jesus has become the guarantee of a better covenant. Read in that sequence, verse 20 is the hinge: it names the oath that makes Jesus’s priesthood a firmer foundation than the old system could offer.

(WEB)
This is the verse the writer of Hebrews quotes to establish Jesus as a priest in the order of Melchizedek. Reading it alongside Hebrews 7:20 shows the original promise that the author is building upon and why the oath matters so much.
Hebrews 7:22
By so much, Jesus has become the collateral of a better covenant.

The verse that follows directly identifies Jesus as the guarantee of a better covenant. It shows how the oath in verse 20 leads to a new agreement between God and his people that rests on a stronger foundation.
A Short Prayer From Hebrews 7:20
Lord, you have made your commitments to your Son with a certainty that does not waver. When my own promises feel weak and my confidence in you wavers, remind me that your word stands firm. Help me to rest in the priesthood of Jesus, who lives to intercede for me. Shape my trust so that it grows steadier each day, and teach me to keep my word with the same faithfulness you show. Amen.
