Thou hast turned for me my mourning into dancing: thou hast put off my sackcloth, and girded me with gladness; Psalms 30:11
Then shall the virgin rejoice in the dance, both young men and old together: for I will turn their mourning into joy, and will comfort them, and make them rejoice from their sorrow. Jeremiah 31:13
"Dancing is primarily a physical and visual means of praising, honoring and thanking God. In the Bible it is often combined with song and instrumentation. Movement joins human and inanimate sound to praise God. Dance is one way of thanking and confessing God “with tambourine and dance;…Let everything that breathes praise the LORD!” (Ps 150;4, 6; 149:3 NRSV).
Dancing and instrumentation are related to prophecy. Miriam the prophetess commanded the women of her time to thank God for making them victorious over their Egyptian enemies (Ex. 15:20-21). The context here is a post battle victory celebration, usually led by women meeting returning warriors. This is also the proper understanding of Isaiah 52:7, which should be translated “How beautiful are the dancing feet of the women [a feminine participle in Hebrew] who spread the good news of peace”).
Dancing was used to celebrate God’s victory in battle and the human “weapons” who were used by God (Judg 11:34; 1 Sam 18:6-7; 21:aa; 29:5). The prophets who met Saul also danced and played instruments (1 Sam 10:5)….
Dance in the Bible symbolizes praise, freedom and equality. An apt summary of its significance is found in the personification of wisdom, a crucial quality needed by artists (Ex 28:3; 31:3; 6; 35:10). Wisdom itself dances, makes sport, laughs. As God created the world, Wisdom was God’s architect, daily dancing before God’s face (Prov. 8:30). God created the world with a dance-like joy, and we humans are to respond with a joyful dance."
