Understanding Psalm 122:3 in Depth: Unity in God’s City

Context of Psalm 122:3

Psalm 122 is a song of ascent, one of the psalms Israelites would sing as they traveled up to Jerusalem for worship, and it captures the joy and meaning of gathering in God’s presence.

These songs were sung by pilgrims making their way to the temple, and this particular psalm begins with excitement - 'I was glad when they said to me, “Let us go to the house of the Lord!”' - showing how much they looked forward to being together in worship. Verse 3 says Jerusalem is not merely about bricks and walls. It symbolizes unity, showing that the Israelite tribes were linked by faith and shared purpose rather than geography. The city stood strong because God’s people stood together, gathering 'as was decreed for Israel, to give thanks to the name of the Lord' (verse 4).

This sense of unity rooted in worship sets the stage for the prayer that follows: 'Pray for the peace of Jerusalem,' because true peace comes not from walls alone, but from God’s people staying bound together in love and loyalty to Him.

Unity in Structure and Purpose

The image of Jerusalem highlights spiritual and communal unity, not merely its physical structure.

This phrase is an example of synthetic parallelism - a common poetic device in the Psalms - where the second part of the line expands and deepens the first. Here, 'built as a city' is clarified and elevated by 'bound firmly together,' shifting focus from architecture to the unbreakable connection among God’s people.

True unity isn’t just living close - it’s being bound together by a shared love for God and His purposes.

Verse 4 shows the practical outworking of this unity: 'the tribes go up, the tribes of the Lord... to give thanks to the name of the Lord.' Their togetherness wasn’t based on politics or convenience, but on shared worship and obedience to God’s command. Verse 5 adds that justice and leadership ('thrones for judgment') were established there, showing that unity supports both spiritual and social order. This kind of cohesion - rooted in reverence for God - creates peace that lasts, which is why the psalmist immediately calls for prayer for Jerusalem’s peace in verse 6.

The Heart of True Unity

This psalm shows us that real unity isn’t built on convenience or shared interests, but on a shared love for God and His house.

True unity starts not with agreements or plans, but with hearts drawn together by God.

The tribes came together not because they had to, but because they wanted to worship the Lord together - 'to give thanks to the name of the Lord' (verse 4). In the same way, Jesus prayed for His followers to be one, 'so that the world may know that you sent me and loved them even as you loved me' (John 17:23), showing that unity is both a sign of God’s presence and a reflection of His love.

Unity Today: The Church as God's City

This ancient vision of a united Jerusalem points forward to the church today, showing us what God has always wanted: a people bound together not by walls, but by worship and His presence.

The writer of Hebrews says we haven’t come to a physical mountain or city, but to 'Mount Zion and the city of the living God, the heavenly Jerusalem' (Hebrews 12:22-24), where countless angels and the spirits of the righteous are gathered in perfect unity. And in Revelation 21, John sees the new Jerusalem coming down from heaven, 'prepared as a bride adorned for her husband' (Revelation 21:2), a city where God dwells with His people forever - no temple needed, because His presence fills everything.

The church isn’t held together by buildings or programs, but by our shared life in Christ - just like the heavenly Jerusalem described in Revelation.

So what does this look like for us? It means choosing unity over being right, like when you forgive a friend at church instead of holding a grudge, or when you serve alongside someone who votes differently than you because you both love Jesus more. It means making time for worship together rather than streaming a service alone, because gathering helps us stay connected. When we live this way, we become a living preview of that coming city - where peace isn’t enforced, but flows from hearts held together by God.
