1 Samuel 20:41

David arose out of a place, &c.— David, coming from the south, fell on his face. Houbigant. From the south of the stone Ezel. David fell on his face, in reverence to his friend, as the king's son. They kissed one another, and wept one with another, until David exceeded. So that there was great lamentation. Houbigant. Their separation could not be made without many tears on both sides. David must have been affected in an especial manner. He lost all: friend, wife, parents, country; and, that which to a heart like his was the severest stroke, he was banished from the altar and service of his God. See ch. 1 Samuel 26:19. There cannot be any thing more pathetic and tender, than this simple and unaffected relation of the parting of these friends.
