Who came to Nachal ha'Besor, and who remained?
Rashi: All 600 men came. Some were tired, and remained [there]. Radak - the verse is abbreviated. They all came; 400 crossed the river, and the rest remained there and guarded the Kelim. 1 The pursuers needed only Kelim needed to fight.
Malbim: Divrei ha'Yamim 1 12 tells that many Gibprim came to David in Tziklag from Binyamin and Menasheh, both when he was taking refuge from Sha'ul, and when he went with Pelishtim against Sha'ul, but in the end, did not help them. They were in addition to the 600 men David had beforehand. These additions remained in Tziklag, for their wives and children were not taken captive, for they were not there.
Malbim: They did not return to their houses. (The entire city was burned! Does Malbim refer to their houses where they lived before they came to David? - PF)
