Hebrews 6:13

“For when God made a promise to Abraham, since he could swear by none greater, he swore by himself,”

Verse in context — Hebrews 6

We desire that each one of you may show the same diligence to the fullness of hope even to the end,

that you won't be sluggish, but imitators of those who through faith and patience inherited the promises.

For when God made a promise to Abraham, since he could swear by none greater, he swore by himself,

saying, "Surely blessing I will bless you, and multiplying I will multiply you.

Thus, having patiently endured, he obtained the promise.

Jesus as the ultimate High Priest and fulfillment of the Old Covenant.
