Psalm 72 is a prayer for blessing upon God's anointed king, probably intended for use in a liturgy for coronation. Later Jewish traditions and the early church saw in it a description of Messiah's righteous reign. The psalm expresses the people's desire that God so endow the king that righteousness and justice will characterize his reign (v. 1). This king will be worthy of high praise, for he will defend the poor and crush the oppressor (st. 1); his reign of refreshing peace and blessing will extend "over every nation" (st. 2). All nations will submit to him and bring him tribute (st. 3). He will rescue the poor, oppressed, and needy, for they are "precious in his sight" (st. 4). Prayers for the longevity and prosperity of his kingdom and praise for him will never cease (st. 5). His name will endure forever, as will his blessings among all nations, invoking eternal praise of the God whose glory fills creation (st. 6; see also Ps. 101).
Psalter Hymnal Handbook
Stanza 1 proclaims immediately that the Lord’s anointed one is “great David’s greater Son!” Belgic Confession, Article 18 also traces his lineage back to David: “…the fruit of the loins of David…descended from David…the seed of David; the root of Jesse.”
And yet, the rule of the promised descendent of David, Jesus, will only begin “in the time appointed” (stanza 1). This truth is also told in Belgic Confession, Article 18: God fulfilled his promise “at the time appointed.”
Stanza 4 says, “all nations shall adore you,” a truth that is rooted in the prediction that the Messiah was coming for “all nations.” Heidelberg Catechism, Lord’s Day 21, Question and Answer 54 professes that the Son of God gathers his church “out of the entire human race,” a church that “is not confined, bound, or limited to a certain place or certain people. But it is spread and dispersed through the entire world...” (Belgic Confession, Article 27).
The song concludes in stanza 4 picturing “a kingdom without end,” a truth that parallels Our World Belongs to God, paragraph 44: “Jesus Christ rules over all,” “His kingdom will come, and the Lord will rule” (paragraph 55). Our Song of Hope, stanza 21 professes: “There will be a new heaven and a new earth, and all creation will be filled with God’s glory.”
