20 And [kai] inasmuch as [kata] [hosos] not [ou] without [choris] an oath [horkomosia] he was made priest:
21 (For [gar] those priests [hiereus] were [men] [eisi] made [ginomai] without [choris] an oath [horkomosia]; but [de] this with [meta] an oath [horkomosia] by [dia] him that said [lego] unto [pros] him [autos], The Lord [kurios] sware [omnuo] and [kai] will [metamellomai] not [ou] repent [metamellomai], Thou [su] art a priest [hiereus] for [eis] ever [aion] after [kata] the order [taxis] of Melchisedec [Melchisedek]:) KJV-Interlinear
20 And inasmuch as it was not without an oath 21 (for they indeed became priests without an oath, but He with an oath through the One who said to Him, 'The Lord has sworn And will not change His mind, 'Thou art a priest forever''); NASB
There are only two priest organizations which have been recognized by the Bible - the Levites and Christ. Both had a specific role in history. No other priesthood in history is utilized for comparison within the scriptures. All false priesthood's are excluded for obvious reasons.
The first represented the nature of the reality of the priest to come. The first, the Levitical priesthood, was but a temporary group. When a priest died, his son took his place until his death and so that priesthood continued from generation to generation.
Those priests could not guarantee their own existence, nor their own perpetuation, nor any security of any kind to the general population. They did not have an oath which secured their existence. They did not have an oath which secured anything that they did.
Nowhere in the Bible is the line of Aaron given an oath from God. Nowhere in the Bible did God guarantee their continuation as priests forever. In fact God never suggested, to Aaron or to anyone else, that their priesthood would be anything but temporary.
Because they were the recipients and the custodians of scripture, the Israelites probably thought that their way of life, their priesthood, was a permanent one, but they had no basis in the scriptures to support that idea.
But with Christ He swore an eternal priesthood, as David wrote in Psa. 110:4.
4 The LORD has sworn and will not change His mind, 'Thou art a priest forever According to the order of Melchizedek.' NASB
God, through the writer David, emphasizes that God, 'will not change His mind.' The oath does not represent greater truthfulness to what God says, but puts the emphasis on its permanence.
When God made His covenant promise to Abraham, He did so with an oath. This promise was unconditional and eternal.
16 and said, 'By Myself I have sworn, declares the LORD' NASB
God wanted Abraham, David, and all the world, to know that His promise was permanent.
Now is the time to post a prayer.
