And Samuel said, gather all Israel to Mizpeh
Not Mizpeh in Gilead, on the other side Jordan, but a city which lay on the borders of Judah and Benjamin, where the tribes met on the account of the Levite's concubine, ( Judges 20:1 ) . This order Samuel gave by messengers sent to the several tribes, or the heads of them, to meet him at this place:
and I will pray for you unto the Lord;
no doubt he prayed for them privately, that the reformation begun might be carried on, and appear to be sincere, and hearty, and general, and uersal; but he was desirous that they might appear in a body, and join with him in public prayer for their spiritual and temporal welfare; that they might have true repentance for their sins, reform from them, and have remission of them, and be delivered out of the hands of their enemies.
