Verses 2-6 give reason to worship and sing to God. Our God builds the holy city (for Israel it was the earthly Jerusalem the place of God’s presence and where God’s holy people dwell, but for believers there will be a showcasing of the holy city in the future). The Lord is compassionate especially to the outcasts, brokenhearted, and the wounded. To those that are in desperate need, God reveals himself and draws them into his holy presence. The power of God is incredibly described as he is the same God that created the heavens, and so knows all of his creation intimately.
