* Psalm 30:11-12: "You have turned my mourning into dancing; You have put off my sackcloth and clothed me with gladness, That my soul may sing praise to You, and not be silent. O Lord my God, I will give thanks to You forever."
* Psalm 149:3: "Let them praise His name with the dance; Let them sing praises to Him with the timbrel and harp."
Additionally, the Bible often uses dance as a metaphor for joy and praise. For example:
* Exodus 15:20-21: "Then Miriam the prophetess, the sister of Aaron, took the timbrel in her hand; and all the women went out after her with timbrels and with dances. And Miriam answered them, 'Sing to the Lord, for He has triumphed gloriously; The horse and its rider He has thrown into the sea.'"
* 2 Samuel 6:14-15: "And David danced before the Lord with all his might; and David was wearing a linen ephod. So David and all the house of Israel brought up the ark of the Lord with shouting and with the sound of the trumpet."
While these passages do not specifically address the topic of Christian dance at weddings, they suggest that dance can be an appropriate expression of joy and praise to God.
