1 Samuel 30:9

So David went, he and the six hundred men that were with him ,.... Encouraged by the oracle of the Lord:

and came to the brook Besor ; which Adrichomius F17 Theatrum Terrae Sanct. p. 133. places in the tribe of Simeon; it is thought to be near Gaza. Aristaeus F18 Hist. 72. Interpret. p. 41. speaks of brooks that flowed by Gaza and Ashdod, places that belonged to the Philistines; some take it to be the river of the wilderness in Amos; see Gill on Amos 6:14 ,

where those that were left behind stayed : or a part of them were left, as the Targum; all the six hundred came to this brook, but two hundred of them were left here, 1 Samuel 30:10 shows, and stayed here till the rest returned; for this is not to be understood of any that were left behind at Ziklag, for all came from thence to this brook.
