Either some of the Canaanites that dwelt near Tabor, or some spies that Sisera had out; though some think the Kenites told him, who were at peace with Jabin, Judges 4:17; yet whether out of good will or ill will cannot be said: however, so it was ordered by the providence of God, that by some means or another Sisera should be informed
that Barak the son of Abinoam was gone up to Mount Tabor; and no doubt at the same time he was told the number of men that went with him; from whence he might well conclude, that such a warlike man, with such a force collected together, and having posted himself in an high and strong mountain, must have some design to cause a revolt of Israel from Jabin his prince.
