'Knelt' in the Bible

When the servant had left, David got up from beside the mound, knelt with his face to the ground, and bowed three times. Then they kissed each other and they both wept, especially David.

Then David got up afterward and went out of the cave and called after Saul, "My lord the king!" When Saul looked after him, David knelt down [with his] face to the ground and bowed down.

Then he said to her, "What [is] his appearance?" She said, "An old man [is] coming up, and {he is wrapped in a robe}." Then Saul realized that it was Samuel, and he knelt [with] his face to the ground and bowed down.
