2 Samuel 6:21

And David said to Michal, “It was before the Lord, who chose me above your father and above all his house, to appoint me as prince over Israel, the people of the Lord—and I will celebrate before the Lord.

David has just danced naked before The Lord as the ark of the covenant was being brought to his home. Michal, his wife, seeing his nakedness became angry and jealous.  The problem lies in the fact that she was not praising God right along with him. If she had been equally yoked she would have known the reason for David's nakedness. Instead, because of her fleshly response, she is struck barren for the rest of her life. We must be lead by the spirit especially in our praise.
