I shall be anointed with fresh oil — connects to the Lord Jesus Christ. Let us begin by distinguishing between two different ways to anoint in the Old Testament. Samuel anointed Saul with a vial of oil, not with a horn of oil.
Side Note: Vial of Oil versus Horn of Oil.
Then Samuel took a vial of oil, and poured it upon his head, and kissed him, and said, Is it not because the LORD hath anointed thee to be captain over his inheritance? (1st Samuel 10:1)
Vials are associated with the wrath of God. (There is a lot more in the placement of the word vials, but for this article I just want to concentrate on the fundamental connection of vials to the wrath of God.) The words vial and/or vials occur in the book of the Revelation of Jesus Christ twelve times all connected to judgment.
And one of the four beasts gave unto the seven angels seven golden vials full of the wrath of God, who liveth for ever and ever. (Revelation 15:7)
And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the vials of the wrath of God upon the earth. (Revelation 16:1)
King David and his son, king Solomon, were both anointed with oil from a horn.
And the LORD said unto Samuel, How long wilt thou mourn for Saul, seeing I have rejected him from reigning over Israel? fill thine horn with oil, and go, I will send thee to Jesse the Bethlehemite: for I have provided me a king among his sons. (1st Samuel 16:1)
Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the LORD came upon David from that day forward. So Samuel rose up, and went to Ramah. (1st Samuel 16:13)
And Zadok the priest took an horn of oil out of the tabernacle, and anointed Solomon. And they blew the trumpet; and all the people said, God save king Solomon. (1st Kings 1:39)
End of Side Note – Vial of Oil versus Horn of Oil.

Anointing
There are 12 references to anointing in the Old Testament specific to priests and kings. There are references to 5 priests and 7 kings being anointed. Twelve (12) being the number of governmental perfection in God’s program. One of the interesting things about anointing is that Saul was the 6th individual anointed. (Six is the number of man.) David was the 7th individual who was anointed (beginning with Aaron). (Seven is the number of God’s perfection in accomplishment and in all of His actions: the perfection of deity.) Saul was the king selected by the people, and God allowed it to be so to show that man is not capable of discernment. But the thing displeased Samuel, when they said, Give us a king to judge us. And Samuel prayed unto the LORD. (1st Samuel 8:6) And the LORD said unto Samuel, Hearken unto the voice of the people in all that they say unto thee: for they have not rejected thee, but they have rejected me, that I should not reign over them. (1st Samuel 8:7) Nevertheless the people refused to obey the voice of Samuel; and they said, Nay; but we will have a king over us; (1st Samuel 8:19) David was the man after God’s own heart. I have found David my servant; with my holy oil have I anointed him: (Psalm 89:20) One more notable fact: David was anointed three times.
