Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows.
Iniquity, х adikian (G93)] - 'unrighteousness.' So 'Aleph (') read 'lawlessness' х anomian (G458)].
Therefore - because God loves righteousness and hates iniquity.
God, even thy God. Jerome, Augustine etc., translate (Psalms 45:7) 'O God, thy God hath anointed thee,' whereby Christ is addressed as God. This probably the Hebrew there means, and also the Greek here: it is likely the Son is addressed "O God," as in Hebrews 1:8. The anointing meant is not that at His baptism, when He solemnly entered on His ministry for us; but that with the "oil of gladness" or 'exulting joy' (triumph, the consequence of His manifested love of righteousness and hatred of iniquity), wherewith, after His triumphant completion of His work, He has been anointed by the Father "above His fellows" (not only above us, the adopted members of God's family, whom 'He is not ashamed to call His brethren;' but above the angels, partakers with Him, though infinitely His inferiors, in the holiness and joys of heaven; "sons of God," and angel - "messengers," though subordinate to the Divine Angel - "Messenger of the covenant").
Thus He is antitype to Solomon, 'chosen of all David's sons to sit upon the throne of the kingdom of the Lord over Israel,' even as his father David was chosen before all the house of his father's sons. The image is from the custom of anointing guests at feasts (Psalms 23:5); or rather of anointing kings: not until His ascension did He assume the kingdom as Son of man. A fuller accomplishment is yet to be, when He shall be VISIBLY the anointed king over the whole earth (set by the Father) on His holy hill of Zion (Psalms 2:6; Psalms 2:8). So David, His type, was first anointed at Bethlehem (1 Samuel 16:13; Psalms 89:20); again at Hebron, first over Judah (2 Samuel 2:4), then over all Israel (2 Samuel 5:3): not until Saul's death did he enter on his actual kingdom; as not until after Christ's death the Father "set Him at His own right hand ... far above all principality" (Ephesians 1:20-21). The 45th psalm in its first meaning was addressed to Solomon; but the Holy Spirit inspired the writer to use language applying in its fullness to the antitypical Solomon, the true Read of the theocracy.
