And they showed Sisera,.... 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.
As soon as Sisera received tidings of the march of Barak to Mount Tabor, he brought together all his chariots and all his men of war from Harosheth of the Goyim into the brook-valley of the Kishon. Then Deborah said to Barak, "Up; for this is the day in which Jehovah hath given Sisera into thy hand. Yea (הלא, nonne, as an expression indicating lively assurance), the Lord goeth out before thee," sc., to the battle, to smite the foe; whereupon Barak went down from Tabor with his 10,000 men to attack the enemy, according to Judges 5:19, at Taanach by the water of Megiddo.
They - That is, this people dwelling there, or his spies.
