Thou art fairer than the children of men - That is, Thou art more fair and comely than men; thy comeliness is greater than that which is found among men. In other words, Thou art beautiful beyond any human standard or comparison. The language, indeed, would not necessarily imply that he was not a man, but it means that among all who dwell upon the earth there was none to be found that could be compared with him. The Hebrew word rendered “thou art fairer” - יפיפית yāpeyāpiytha - is a very unusual term. It is properly a reduplication of the word meaning “beautiful,” and thus means to be very beautiful. It would be well expressed by the phrase “Beautiful - beautiful - art thou above the children of men.” It is the language of surprise - of a sudden impression of beauty - beauty as it strikes at the first glance - such as the eye had never seen before. The impression here is that produced by the general appearance or aspect of him who is seen as king. Afterward the attention is more particularly directed to the “grace that is poured into his lips.” The language here would well express the emotions often felt by a young convert when he is first made to see the beauty of the character of the Lord Jesus as a Saviour: “Beautiful; beautiful, above all men.”
Grace is poured into thy lips - The word here rendered “is poured” means properly to pour, to pour out as liquids - water, or melted metal: Genesis 28:18; 2 Kings 4:4. The meaning here is, that grace seemed to be spread over his lips; or that this was strikingly manifest on his lips. The word grace means properly favor; and then it is used in the general sense of benignity, kindness, mildness, gentleness, benevolence. The reference here is to his manner of speaking, as corresponding with the beauty of his person, and as that which particularly attracted the attention of the psalmist: the mildness; the gentleness; the kindness; the persuasive eloquence of his words. It is hardly necessary to remark that this, in an eminent degree, was applicable to the Lord Jesus. Thus if is said Luke 4:22, “And all bare him witness, and wondered at the gracious words which proceeded out of his mouth.” So John 7:46 : “Never man spake like this man.” See also Matthew 7:29; Matthew 13:54; Luke 2:47.
Therefore God hath blessed thee for ever - In connection with this moral beauty - this beauty of character - God will bless thee to all eternity. Since he has endowed thee with such gifts and graces, he will continue to bless thee, forever. In other words, it is impossible that one who is thus endowed should ever be an object of the divine displeasure.
