'Prostrated' in the Bible

Then David got up, went out of the cave, and called out to Saul: "Your majesty!" Saul looked behind him, and David bowed down with his face to the ground and prostrated himself.

She got up, prostrated herself face down on the ground, and replied, "Your servant would be a slave to wash the feet of your majesty's servants."

Saul told her, "What does he look like?" She said, "An old man is coming up, and he's wrapped in a robe." Saul knew that it was Samuel, and he bowed low to the ground and prostrated himself.
