"Prophet, Priest, King", Part 2

A Psalm of David. The Lord says to my Lord: “Sit at my right hand, until I make your enemies your footstool. ² The Lord sends forth from Zion your mighty scepter. Rule in the midst of your enemies! ³ Your people will offer themselves freely on the day of your power, in holy garments; from the womb of the morning, the dew of your youth will be yours. ⁴ The Lord has sworn and will not change his mind, “You are a priest forever after the order of Melchizedek. ⁵ The Lord is at your right hand; he will shatter kings on the day of his wrath. ⁶ He will execute judgment among the nations, filling them with corpses; he will shatter chiefs over the wide earth. ⁷ He will drink from the brook by the way; therefore he will lift up his head. Psalm 110:1-7

The Lord says to my Lord: “Sit at my right hand, until I make your enemies your footstool...” Psalm 110:1

The Lord has sworn and will not change his mind, “You are a priest forever after the order of Melchizedek” Psalm 110:4

1. The Lord would appoint Him to be a priest by an irrevocable oath!
2. God declared Him to be a priest forever!
3. He would be a priest after the order of Melchizedek!

¹⁷ After his return [Abraham’s] from the defeat of Chedorlaomer and the kings who were with him, the king of Sodom went out to meet him at the Valley of Shaveh (that is, the King's Valley). ¹⁸ And Melchizedek king of Salem brought out bread and wine.
(He was priest of God Most High.)¹⁹ And he blessed him and said, “Blessed be Abram by God Most High, Possessor^[b] of heaven and earth; ²⁰ and blessed be God Most High, who has delivered your enemies into your hand!” And Abram gave him a tenth of everything. Genesis 14:17-20

For this Melchizedek, king of Salem, priest of the Most High God, met Abraham returning from the slaughter of the kings and blessed him, ² and to him Abraham apportioned a tenth part of everything. He is first, by translation of his name, king of righteousness, and then he is also king of Salem, that is, king of peace. ³ He is without father or mother or genealogy, having neither beginning of days nor end of life, but resembling the Son of God he continues a priest forever. Hebrews 7:1-3

⁴ See how great this man was to whom Abraham the patriarch gave a tenth of the spoils! ⁵ And those descendants of Levi who receive the priestly office have a commandment in the law to take tithes from the people, that is, from their brothers, though these also are descended from Abraham. ⁶ But this man who does not have his descent from them received tithes from Abraham and blessed him who had the promises. ⁷ It is beyond dispute that the inferior is blessed by the superior. Hebrews 7:4-7

²³ The former priests were many in number, because they were prevented by death from continuing in office, ²⁴ but he holds his priesthood permanently, because he continues forever. ²⁵ Consequently, he is able to save to the uttermost^[b] those who draw near to God through him, since he always lives to make intercession for them.
Hebrews 7:23-25
