Dancing - Vine's Expository Dictionary of New Testament Words
Dancing[ 1,,G5525, choros ]
Eng., chorus", primarily denoted "an enclosure for dancing;" hence, "a company of dancers and singers." The supposition that the word is connected with orcheo by metathesis (i.e., change of place, of the letters ch and o) seems to be without foundation. The word is used in Luke 15:25.
