vs. 6. "Yet have I set my king upon my holy hill of Zion."
The Lord God's king and Messiah is Jesus Christ. God's holy hill of Zion is God's people, his church. (Psalm 48).
7. "I will declare the decree: the LORD hath said unto me, Thou [art] my Son; this day have I begotten thee."
The Lord God speaks of Jesus here. Jesus is the only begotten son of God.
9. "Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter's vessel."
Jesus has been ordained to judge the earth, (Acts 10.42)
12. "Kiss the Son, lest he be angry, and ye perish [from] the way, when his wrath is kindled but a little. Blessed [are] all they that put their trust in him."
Here the scripture warns us all to, 'kiss the son', or acknowledge that he is Lord and God, or else, perish. And a blessing rests on those that believe on him.
The Psalm looks beyond David to the Messiah. Christians believe this was fulfilled in Jesus Christ.
Messianic Psalms make reference to the Messiah, to Jesus Christ. The Psalms make predictions about the Messiah's birth, his person, his life, his death, burial, and resurrection, his ascension into heaven, his priestly ministry, his second coming, his victory over his enemies, and his universal reign on Earth.
Jesus Christ was and is the Lord of Glory and the king of kings whose understanding is infinite, (Psalm 147.5). Also he created all things, (Hebrews 2.2)
Psalm 40 is a prophetic psalm of Jesus, as are many others in the book of Psalms, as Psalm 22 and 23.
Luke 20 41And he said unto them, How say they that Christ is David's son? 42And David himself saith in the book of Psalms, [Jesus here quoted Psalm 110] The LORD said unto my Lord, Sit thou on my right hand, 43 Till I make thine enemies thy footstool. 44 David therefore calleth him Lord, how is he then his son? In talking to the scribes of the Sadducee sect, Jesus asked the rhetorical question, "How say they that Christ is David's son?" He then asked, "David therefore calleth him Lord, how is he then his son [ descendant]?In the context of the previous section, where the Sadducees were trying to trap Jesus with a question they thought he could not answer, He then asked them a difficult question, which they could not answer without understanding the Bible. Christ is paradoxically, a descendant of King David ( his 'son'), and His Lord, the Messiah. The Saduccees did not understand that.It was at the time commonly believed that in "the LORD said unto my Lord" "my Lord" referred to the expected Messiah. The Messiah was to be a descendant of David, as well as his God.
As Jesus the Messiah (the Christ) coming in the flesh in fulfillment of Old Testament prophecy and promise (for ex - Genesis 3:15 or Isaiah 53) to die for our sins (Daniel 9)and that He would rise from the dead (Psalm 16:10) and that He will come again to judge the nations (Zechariah 12:10)
There are at least four. Jesus (the son of God) and Bar-Jesus, the Jewish sorcerer and false prophet mentioned in Acts 13:6. Jesus who is called Justus in Colossians 4:11. And Jesus called Barabas, who was set free instead of Jesus called the Christ
Jesus referenced David in several contexts, highlighting his significance in Jewish history. In the Gospels, He pointed out that David called the Messiah "Lord" in Psalm 110, emphasizing the divine authority of the Messiah. Additionally, Jesus noted that David and his companions ate the consecrated bread when they were in need, illustrating His teaching on mercy and the spirit of the law over ritual. Overall, Jesus used David to affirm His own identity and to challenge religious legalism.
Psalm 22.
The Hebrew word "sukh" (Greek: "aleipho") were used for normal 'greasing, or rubbing on of oil'(Ruth 3:3; John 11:2), but for a 'special anointing' , to accomplish a certain purpose, the word "Messiah" (mashach / mashiach) was used. (Exodus 30:30; Luke 4:18; Acts 4:26).Thus, Aaron, Moses and Jesus could all be called "Messiah", or 'anointed' for a special purpose. (Messiah+Christ, both mean anointed)(Leviticus 8:12 / Psalm 133:2)
(Psalm 83:18) That people may know that you, whose name is Jehovah, You alone are the Most High over all the earth.
Psalm 19 describe God's "law" as "perfect" and "sure." God's "statutes" are described to be "right."
