'Play' in the Bible

And Abner said to Joab, Let the young men now arise, and play before us. And Joab said, Let them arise.

And David said unto Michal, It was before the LORD, which chose me before thy father, and before all his house, to appoint me ruler over the people of the LORD, over Israel: therefore will I play before the LORD.

Be of good courage, and let us play the men for our people, and for the cities of our God: and the LORD do that which seemeth him good.
