1 Samuel 13:15

And Samuel arose,.... Seemingly in wrath and displeasure, not staying to offer up the peace offerings which remained; and though no mention is made of Saul's going with him, yet it seems as if he did, or at least quickly followed him, as appears from the next verse:

and got him up from Gilgal unto Gibeah of Benjamin; the native place of Saul, thereby directing Saul where he should go, and which might be a stronger place than Gilgal; or however where he might expect to be joined by more persons of his own tribe, as well as in the first place protect and defend that; and it looks by Samuel's going thither, though he was displeased with Saul, yet that he did not intend to forsake him directly and entirely:

and Saul numbered the people that were present with him, about six hundred men: which was done either before he left Gilgal, or as soon as he came to Gibeah; so great a desertion was there from him, that of the 3000 first chosen by him, and of the people after called and gathered to him at Gilgal, only six hundred remained with him; a small number indeed to encounter so large an army the Philistines had brought into the field, and which therefore Saul could not face.
