Thou art fairer than the children of men   Psa 45:2

Psalm 45 is a wedding hymn, composed for the marriage of a king to a king’s daughter. Some see it referring only to Solomon and Pharaoh's daughter, but more focussed spiritual eyes see here a reference to the Lord Jesus. That the Psalm is Messianic is confirmed in Heb 1:8-9 with reference to verses 6 & 7 of the Psalm.

If, as the hymn writer suggests (Believers 342, v.1), it was  possible for all the virtues of the most excellent people to be bound together into one person, that person could not rival our Lord. The language means that among all who dwell upon the earth there is none to be found that can be compared with Him. The Hebrew word rendered “Thou art fairer” means to be very beautiful. It could be expressed by the phrase “Beautiful - beautiful - art thou above the children of men.”  This “beauty” should not be understood of His divine beauty or His glory, as the only begotten of the Father, but of the beauty of His human nature, which being without sin, and full of wisdom, grace, and holiness, exceeds that of  all the sons of Adam. He cannot be compared with other men - He must be contrasted. He is perfection personified! He has been anointed with the oil of myrrh and aloes, and cassia (v.8).  His love is better than wine, His Name is as ointment poured forth (Song 1:2-3).

Among the children of men, many have through grace been lovely in character, yet they have each had a flaw, but in the Lord Jesus we behold every feature of a perfect character. As another exclaims of Him, "He is altogether lovely", Son_5:16.
