40And Jonathan gave his artillery unto his lad, and said unto him, Go, carry to the city.
41as soon as the lad was gone, David arose out of toward the south, and fell on his face to the ground, and bowed himself three times: and they kissed one another, and wept one with another, until David exceeded.
