David is the same person the Israelites sing and dance about when they sing this song:
Then Aaron’s sister, the woman prophet Miriam, took a tambourine. Miriam and the women began singing and dancing. Miriam repeated the words,
Don’t wake up your neighbor early in the morning with a shout of, “Good morning!” He will treat it like a curse, not a blessing.
That day David ran away from Saul. David went to Achish king of Gath.
