Hebrews 7:22

“By so much was Jesus made a surety of a better testament.] Or “covenant”, for the word signifies both; and what is intended may be called both a testament and a covenant; a testament, because it is founded in the good will and pleasure of God, and respects an inheritance bequeathed by God the Father to his children, which was confirmed and comes to them by the death of Christ the testator; and a covenant, it being a compact or agreement made by the Father with Christ, as the representative of all the elect; in which promises and blessings of all sorts are provided and secured for them in him; and is called in Scripture a covenant of life and peace, because these are things concerned in it;…”

“surety--ensuring in His own person the certainty of the covenant to us. This He did by becoming responsible for our guilt, by sealing the covenant with His blood, and by being openly acknowledged as our triumphant Saviour by the Father, who raised Him from the dead. Thus He is at once God's surety for man, and man's surety for God, and so Mediator between God and man (Heb 8:6). better-- Heb 8:6; Heb 13:20, "everlasting." testament--sometimes translated, "covenant."

Was Jesus made a surety - The word “surety” - ἐγγυος enguos - occurs nowhere else in the New Testament nor is it found in the Septuagint. It properly means, a…”

“Of so much better a covenant - Unchangeable, eternal. Was Jesus made a surety - Or mediator. The word covenant frequently occurs in the remaining part of this epistle. The original word means either a covenant or a last will and testament. St. Paul takes it sometimes in the former, sometimes in the latter, sense; sometimes he includes both. Hebrews 7:23”

“7:22 Legally, the one who guarantees (literally the guarantee or the guarantor) refers to the person who bears the risk of another person’s investment or debt.
