18–20 The concluding doxology closes Book II. The Lord is “blessed” (bārûk; NIV, “praise be to”). He is God, the Lord (Yahweh), “the God of Israel,” who has done and will continue to do “marvelous deeds” in behalf of his people (v. 18; cf. 71:14; 86:10; 136:4). Through his “deeds” he has demonstrated his “glorious name” (v. 19; cf. 1 Ch 29:13; Ne 9:5; Isa 63:14) in all the earth (cf. Isa 6:3). Such was also the testimony of Zechariah: “Praise be to the Lord, the God of Israel, because he has come and has redeemed his people” (Lk 1:68).
The congregational response to the doxology is a twofold “Amen” (cf. 106:48; Ne 8:6). They confess that these words are true. The final verse (v. 20) separates the psalms associated with David from those of Asaph (Pss 73–83).
72:18, 19 The Psalm closes with a doxology. The glorious reign of the Lord Jesus is God’s achievement. It is He who brings about these wonderful conditions, as no one else could do. And so it is fitting that His glorious name be praised forever, and that His glory fill the whole earth.
72:19 The filling of the earth with God’s glory will be fulfilled in the consummation (Rev. 21:22–27).
72:19 blessed be his glorious name forever Yahweh’s name is representative of His power and character.
72:18, 19 These magnificent words of benediction mark the conclusion of the psalm, as well as the conclusion of Book II of the Psalms. The repetition of the word blessed, the focus on the name (as in 89:16), and the double Amen all indicate that this psalm was used in the worship of God in His temple.
