This is one of the most quoted psalms in the New Testament. It clearly references to the Messiah.
Verse 1 – The Lord said to my Lord, “Sit at My right hand, till I make Your enemies Your footstool.”
This verse is quoted by Jesus when answering the Pharisees in Matthew 22:41-46.
A lot of people have a vague belief in God, but refuse to accept Jesus as anything more than a great teacher. However, both the Old Testament and the New Testament clearly proclaim the deity of Jesus. This is also quoted in Mark 12:36, 37, where Jesus was explaining He is greater than David.
Then Peter used this psalm to show that the Messiah sits at the right hand of God and is Lord over all (Acts 2:32-35).
Jesus was always and always will be. Look in Genesis 1:26 – Then God said, “Let us make man in Our image.” John 1:1 – In the beginning was the Word (the word was spoken and all creation was made), and the Word was with God, and the Word was God.
John 1:14 – And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth – Jesus!
Verse 2 – The Lord shall send the rod of Your strength out of Zion. Rule in the midst of Your enemies!
Romans 11:26, 27 – And so all Israel will be saved, as it is written: The deliverer will come out of Zion, and He will turn away ungodliness from Jacob. (verse 27) For this is My covenant with them, when I take away their sins.
Verse 3 – Your people shall be volunteers in the day of Your power; in the beauties of holiness, from the womb of the morning, You have the dew of Your youth.
Verse 4 – “You are a priest forever according to Melchizedek.”
God promised an eternal dynasty to David (2 Samuel 7:14-17). Jesus Christ, as a descendant of David and as the Son of God, fulfills the dual roles of King and priest forever (Hebrews 7:17, 21).
This is why Jesus is the only mediator between man and God. He is all we need. Our high Priest is perfect in every way!
Verse 5 – The Lord is at Your right hand; He shall execute kings in the day of His wrath.
Verse 6 – He shall judge among the nations, He shall fill the places with dead bodies, He shall execute the heads of many countries.
There’s coming a day, not just any day, but “The Day of the Lord”, when the wicked rulers and kings will be destroyed.
Verse 7 – He shall drink of the brook by the wayside; therefore He shall lift up the head.
(I have no idea what this verse means, sorry. Maybe it means, the leaders of the those countries will see their destruction coming and they will know from whom it comes.)
