1 Samuel 30:21

And David came to the two hundred men
Left at the brook Besor:

who were so faint that they could not follow David;
or, as the Targum, were restrained from going over after him; either through faintness of spirits, and weakness of body, or through the order of David that they should not follow him; and which seems to receive some countenance from what follows:

whom they had made also to abide at the brook Besor;
to guard the passage there, and to tarry by and keep the stuff:

and they went forth to meet David, and to meet the people that [were]
with him;
to congratulate them upon the victory they had obtained, and to see and receive their wives and children, and what portion of the spoil might be divided to them:

and when David came near to the people, he saluted them;
asked them of their welfare, whether they were in better health, and recovered of their faintness and weakness, as it should seem they were, by their coming forth to meet him.
