to whirl: to dance by spinning and turning the whole body, thrown into the motion with full strength.
This verb turns up only twice in the Bible, and both times in the same moment: David bringing the ark of the covenant up to Jerusalem, moving in front of it with everything he has (2 Samuel 6:14, 16). Everything we can say about it therefore comes from the company it keeps and from related languages, not from watching it work across many different settings.
The clues point in one direction, toward turning and spinning:
- The word is built on a doubled pattern that Hebrew tends to use for repeated, back-and-forth, or circling movement.
- Its relatives in Arabic and in later Aramaic mean to go round, to wheel about, to come back around again.
- In 2 Samuel 6:16 it stands next to another rare verb for leaping or skipping (פָּזַז), so it belongs with athletic, whole-body motion.
- When a later writer retold the same scene in 1 Chronicles 15:29, he swapped in the everyday Hebrew word for dancing (רָקַד), which shows how a Hebrew reader heard it.
The standard dictionaries treat "dance" as the shade this particular word takes on rather than its bare core, which they give as something closer to "turn" or "go round." That is why translations reach for "whirling" as readily as for "danced."
Not every ancient reader agreed. The old Greek translation of Samuel, and Josephus after it, took the word to mean striking up music on instruments rather than dancing, and the Aramaic version read it as "praising." A few modern scholars have followed the Greek. Most have not, mainly because of that later retelling and because Michal's contempt at the window makes better sense of a body flinging itself about than of a king plucking strings.
