Am not I a Benjamite - This speech of Saul is exceedingly modest; he was now becomingly humble; but who can bear elevation and prosperity? The tribe of Benjamin had not yet recovered its strength, after the ruinous war it had with the other tribes, Judges 20:29-46.
The tribe of Benjamin, originally the smallest of all the tribes Numbers 1:36, if Ephraim and Manasseh are reckoned as one tribe, had been nearly annihilated by the civil war recorded in Judges 20. It had of course not recovered from that terrible calamity in the time of Saul, and was doubtless literally much the smallest tribe at that time. Nothing could be more improbable, humanly speaking, than that this weak tribe should give a ruler to the mighty tribes of Joseph and Judah.
