1 Samuel 20:21

And, behold, I will send a lad,.... That attended on him, and carried his bow and arrows, and fetched his arrows when he had shot them:

[saying], go, find out the arrows; where they are fallen, and return them:

if I expressly say unto the lad, behold, the arrows [are] on this side of thee, take them; on one side of him, whether the one or the other, which he would bid him take up, and bring them to him:

then come thou; David, out of the place where he hid himself:

for [there is] peace to thee, and no hurt, [as] the Lord liveth; he might appear, and not be afraid of being seen by any, since by this sign he might be assured that Saul was well affected to him, and would show him favour, and do him no injury; and that he might promise himself prosperity and safety, and be assured of it for the present.
