Commentary on Psalms 87

Psalm 87 is a short, exuberant song of Zion, celebrating God's unique choice of Jerusalem as his dwelling place. The psalmist envisions a day when not only Israel but also traditional enemies and distant nations—Rahab (Egypt), Babylon, Philistia, Tyre, and Cush—will be counted as citizens of Zion. The central tension is between God's particular love for one city and his universal purpose to gather all peoples. The chapter ends with a declaration that the source of true joy and life is found in Zion, because God himself makes his home there.

Historical context

Psalm 87 is a 'Psalm of the Sons of Korah,' a guild of temple musicians who served in Jerusalem. While its exact date is uncertain, its themes fit well in the post-exilic period (after 539 BC), when Israel had returned from Babylon and was rebuilding the temple and city walls. The psalm reflects a mature theological vision: God's choice of Zion is not for Israel's exclusive privilege but as a beacon for the nations.

The list of nations is striking. Rahab is a poetic name for Egypt (see Ps 89:10; Isa 30:7). Babylon was the great oppressor. Philistia and Tyre were long-standing neighbors and rivals. Cush (Ethiopia) represents the far south. These were not friendly nations; they were the archetypal 'them' in Israel's story. By naming them as future citizens of Zion, the psalmist is making a radical claim about God's global purposes, anticipating the New Testament vision of a multi-ethnic people of God (Eph 2:11-22; Rev 7:9).

Verse by verse

• 1:

  The psalm opens with a foundational claim: 'On the holy mount stands the city he founded.' The verb 'founded' (yasad) is the same word used for the creation of the earth (Job 38:4). Zion is not a human accident; it is a divine creation, as solid and intentional as the world itself. The 'holy mount' is Mount Moriah, the temple mount in Jerusalem.

• 2:

  'The LORD loves the gates of Zion more than all the dwelling places of Jacob.' This is a startling statement. God loves all of Israel, but he has a special, intense love for Jerusalem. The 'gates' represent the city's security, governance, and public life. This is not favoritism in a petty sense; it is God choosing a specific location as the epicenter of his redemptive plan.

• 3:

  'Glorious things of you are spoken, O city of God.' This verse functions as a refrain or a headline. The psalmist is about to list those 'glorious things.' The phrase 'city of God' (ir ha'elohim) is a title of honor, used elsewhere of Jerusalem (Ps 46:4; 48:1). The city's glory is not in its architecture but in its inhabitant.

• 4:

  God himself speaks: 'I will mention Rahab and Babylon among those who know me.' The verb 'mention' (zakar) often means 'to remember' or 'to call to mind,' but here it has a performative sense: God is publicly acknowledging these nations as his own. Philistia, Tyre, and Cush are then added. The phrase 'This one was born there' refers to being born in Zion—a spiritual citizenship granted by God's declaration.

• 5:

  'And of Zion it shall be said, "This one and that one were born in her."' The psalmist doubles down on the imagery of new birth. The Most High himself will 'establish' (konen) Zion, making her secure. The point is clear: citizenship in God's city is not by natural descent from Abraham but by divine decree. God himself writes the registry.

• 6:

  'The LORD records as he registers the peoples, "This one was born there."' This is the census of the new creation. God keeps a book—the 'book of life' (Ex 32:32; Phil 4:3; Rev 21:27)—and in it, former enemies are listed as native-born citizens of Zion. The verb 'register' (katab) means to write down officially. This is a legal, unchangeable declaration.

• 7:

  The psalm ends with a burst of joy: 'Singers and dancers alike say, "All my springs are in you."' The 'springs' (ma'yan) are sources of water, and in the ancient Near East, water is life. The meaning is that all true life, joy, and refreshment flow from God's presence in Zion. The city is not the source; God is. But the city is the place where that source is found.

Key themes

• Joy and life flowing from God's presence

Application

Psalm 87 confronts any tendency we have to make God's love small or tribal. It is easy to think of the church as a club for people like us. This psalm shatters that notion. God's plan has always been to gather a people from every nation, tribe, and tongue. The 'enemies' of Israel—Egypt, Babylon, Philistia—are named as future citizens of Zion.

For the believer, this means our identity is not ultimately in our ethnicity, nationality, or denomination. It is in being 'born in Zion'—born again into the city of God through faith in Christ (John 3:3; Gal 4:26). The joy of the Christian life is not found in our achievements but in the fact that all our 'springs'—our life, hope, and satisfaction—are in God. When we gather for worship, we are already joining the 'singers and dancers' of the heavenly Zion (Heb 12:22-24).
