Shared ground
These closing lines explain why the whole creation-wide chorus of Psalm 148 should praise Yahweh: his name is uniquely exalted, and his glory rises above every realm the psalm has named (earth and heavens). That is an explicit claim of incomparable status, not merely that Yahweh is “one great god among others” (Psalm 148:13–14).
The focus then narrows from “everyone” to “his people.” The text says God has “lifted up the horn” of his people—language for strengthened power, renewed standing, or restored confidence. It also identifies this praising community as “his saints” and then more specifically as “the children of Israel,” described as “a people near to him.”
Where interpretation differs (only where needed)
1) What “name” emphasizes. Some read “name” mainly as God’s public reputation and renown. Others think it also points to God’s revealed identity and active presence with his people. Both fit the line’s aim: Yahweh is recognized as uniquely above all.
2) What “glory above earth and heavens” means. Many take this as rank—God’s honor is higher than all creation. Others hear a more “visible-display” sense: God’s splendor shows itself in ways that surpass what earth and sky can contain or match. The text itself states surpassing greatness; the difference is how concrete that “glory” is imagined.
3) What “lifted up the horn” refers to. Some read it as victory or national strength. Others read it as recovery after weakness (a restoration of status). The line does not specify the event; it states the outcome: God has raised his people’s strength/standing.
Why the disagreement exists
The key phrases are poetic and compact (“name,” “glory,” “horn,” “near”). They clearly assert God’s supremacy and Israel’s uplift, but they do not spell out how that supremacy is experienced or which historical change produced Israel’s “raised horn,” leaving room for different, still plausible, explanations.
What this passage clearly contributes
It provides the capstone logic for the whole psalm: praise is grounded first in Yahweh’s unmatched exaltation (his name alone; his glory above all realms), and then in a particular relationship: God has acted for “his people,” making Israel—“a people near to him”—a fitting, highlighted voice within the wider chorus of creation’s praise.
