Praise to God and closing note

Psalm 72 as a whole has been asking for an ideal king’s rule and for wide-reaching well-being, ending with world-sized hopes. Verses 18–19 function like a closing doxology: they shift attention from the king and the requests to the God who stands behind any lasting good, and they widen the perspective from Israel to “the whole earth.” Verse 20 is different in kind; it is not praise but a collection note that signals a boundary in the book’s arrangement and invites the reader to notice that these psalms are grouped and edited, not merely individual songs.

The wording assumes Israel’s distinctive worship of Yahweh as the national God (“the God of Israel”), expressed in formal blessing language used in communal settings. The desire that the whole earth be filled with God’s glory fits a setting where Israel understood its God as active beyond local borders, even if Israel’s political reach was limited. The closing notice about “the prayers by David” reflects the compilation of psalms into a larger anthology over time, where older David-linked materials were gathered, arranged, and framed with editorial markers for public reading and worship.

Shared ground

These lines function as the closing praise of Psalm 72 and then an editorial note. The text openly blesses Yahweh as “the God of Israel” and highlights his uniqueness: he alone does “marvelous deeds.” The focus is not on the king anymore, but on God as the source behind any lasting justice, peace, or well-being the psalm has been asking for.

The praise expands from Israel outward. God’s “glorious name” is to be blessed forever, and the horizon becomes global: “Let the whole earth be filled with his glory” (glory). The double “Amen” is a strong confirmation, like a communal “yes.”

Finally, verse 20 is different in kind: it reports that a set of “prayers by David, son of Jesse” has ended. It signals that the Psalms are arranged and edited as a collection, not only individual poems.

Where interpretation differs

1) What “the prayers of David… are ended” means (v. 20). Some read this as meaning the David-related collection in this part of the Psalms has reached its endpoint. Others take it more broadly, as if it claims this is the end of all David’s prayers in the Psalter, which seems harder to square with later psalms also linked with David.

2) What “name” and “whole earth” imply (v. 19). Many agree “name” points to God as he is known and honored, but readers may stress different shades: reputation, revealed identity, or active presence among people. Likewise, “let the whole earth be filled” can be heard as a wish/prayer, a confident expectation, or a liturgical hope voiced in worship.

Why the disagreement exists Verse 20 reads like a headline added at a collection boundary, and boundaries can be interpreted narrowly (“this section”) or broadly (“everything”). In verse 19, the words “name” and “whole earth” are sweeping and poetic; poetry often compresses meaning, leaving room for whether the line is mainly aspiration, prediction, or both.

What this passage clearly contributes The text makes explicit claims about God’s uniqueness, the fittingness of everlasting honor to him, and the global scope of his glory. It also provides a clear window into how the Psalms were handled as an anthology: the worship language (“Amen and amen”) sits right next to a compiling note that marks the end of a set of David-associated prayers (Psalm 72:18–20).
