All the kings of the earth shall praise thee, O Lord,.... Or "let [them] confess", or "praise thee" s; a wish or prayer. Not only the kings known to David, as Kimchi limits it; or that lived in his days, as Hiram and others; but in the latter day, when they shall come to Zion, the church, and be nursing fathers to it, and shall serve and worship the King Messiah, Isaiah 49:23;
when they hear the words of thy mouth; either the promises of it fulfilled not only with respect to David; but the Messiah, and his church and people, in the latter day, even the glorious things spoken thereof: or the doctrines of the Gospel, which are the words of his mouth, and more desirable than thousands of gold and silver; and which, when kings shall hear so as to understand, they will praise the Lord for them; see Isaiah 52:15. The Targum is,
"the words of thy praise.''
