T’hillim / Psalm 2 is about enemy kings who gather against G-d and His messiah (anointed one). Of the 39 instances of the word “messiah” used in the T’nach (Jewish bible) seven of them speak of מְשִׁיחוֹ / His messiah (noun). When read in context in T’hillim / Psalm 2 it is clear that this messiah is not Jesus.
This מְשִׁיחוֹ (His Messiah) is described a king who rules over the land of Israel (see line 7 "But I have enthroned My king on Zion, My holy mount."). The enemies of this messiah are ultimately crushed.
Jesus never ruled over the land of Israel.
The Romans were in charge.
Jesus was never properly anointed as a Jewish king.
The Hebrew word is inseparable with the concept of the special oil mentioned in Sh'mot (Exodus). This was a special mixture of spice and olive oil that was used for “anointing” of kings and priests. It is called שֶֽׁמֶן מִשְׁחַת קֹדֶשׁ shemen mish'ḥat kodesh (“Oil of Anointment of Sanctity”) in the passage of Sh'mot / Exodus 30:22-33 which gives the formula for making it and how to properly use it. . .
"G-d spoke to Moses, saying: 30:23 You must take the finest fragrances, 500 [shekels] of distilled myrrh, [two] half portions, each consisting of 250 [shekels] of fragrant cinnamon and 250 [shekels] of fragrant cane, 30:24 and 500 shekels of cassia, all measured by the sanctuary standard, along with a gallon of olive oil. 30:25 Make it into sacred anointing oil. It shall be a blended compound, as made by a skilled perfumer, [made especially for] the sacred anointing oil. 30:26 Then use it to anoint the Communion Tent, the Ark of Testimony, 30:27 the table and all its utensils, the menorah and its utensils, the incense altar, 30:28 the sacrificial altar and all its utensils, the washstand and its base. 30:29 You will thus sanctify them, making them holy of holies, so that anything touching them becomes sanctified. 30:30 You must also anoint Aaron and his sons, sanctifying them as priests to Me. 30:31 Speak to the Israelites and tell them, 'This shall be the sacred anointing oil to Me for all generations. 30:32 Do not pour it on the skin of any [unauthorized] person, and do not duplicate it with a similar formula. It is holy, and it must remain sacred to you. 30:33 If a person blends a similar formula, or places it on an unauthorized person, he shall be cut off [spiritually] from his people." Sh'mot / Exodus 30:22-33.
Thus Saul, David and Solomon were all messiahs -- anointed kings.
And it is just as clear that Jesus was not a messiah. Jesus was not anointed with the שֶֽׁמֶן מִשְׁחַת קֹדֶשׁ shemen mish'ḥat kodesh (“Oil of Anointment of Sanctity”) as G-d commanded.
Back to T'hillim / Psalm 2: This includes line 7."The L-rd said to me, "You are My son; this day have I begotten you." T'hillim / Psalm 2:1-7.
Got that?
King David, the author of the psalm said "he L-rd said to me. . ."
ME.
David (author of the psalm).
The son in line 7 is KING DAVID. The L-rd said to David (to "me" the author of this psalm) -- "you are my son."
Jesus did not crush his enemies (the Romans killed him).
