The High Priest
For every high priest taken from among men is appointed for men in things pertaining to God, that he may offer both gifts and sacrifices for sins. He can have compassion on those who are ignorant and going astray, since he himself is also subject to weakness. Because of this he is required as for the people, so also for himself, to offer sacrifices for sins. And no man takes this honor to himself, but he who is called by God, just as Aaron was. So also Christ did not glorify Himself to become High Priest, but it was He who said to Him: “You are My Son, Today I have begotten You.” As He also says in another place: “You are a priest forever According to the order of Melchizedek” - Hebrews 5:1-6
Leviticus 8 and 9 are best read with the foreknowledge that Jesus Christ has been anointed THE Priest between God and man - FOREVER.
I see a parallel between Leviticus 8:12, “And he poured some of the anointing oil on Aaron’s head and anointed him, to consecrate him.” and Matthew 26:7, “a woman came to Him having an alabaster flask of very costly fragrant oil, and she poured it on His head as He sat at the table.”
I mention this for one reason: The reaction of the woman’s actions was intense. Judas was outraged at the woman, and Jesus was outraged at Judas. And so far, everything makes sense. Jesus seemed to get excited when He extended the discussion: “[W]herever this gospel is preached in the whole world, what this woman has done will also be told as a memorial to her.” Now her act of worship was commendable, and it did not deserve Judas’ attack. But I didn’t see it as so important that Jesus should go to that length to defend her. As much as I may crave an explanation, God is simply not obliged to supply it.
IF the anointings of Leviticus 8 and Matthew 26 are connected, then Christ as our Priest was at stake, and the woman’s act was hugely important. For wherever the gospel is preached, Jesus Christ is High Priest Forever.
