And when they forgat the Lord their God
The worship of the Lord their God, as the Targum; that is, they fell into idolatry, which is a plain instance and proof of forgetfulness of God; for such that neglect his worship, and serve idols, may be truly said to forget him:
he sold them into the hand of Sisera, captain of the host of Hazor;
who was general of the army of Jabin king of Canaan, who reigned in Hazor, ( Judges 4:2 ) , where they are said to be sold into the hands of Jabin, here into the hands of Sisera; because it is highly probable he was sent against them by Jabin, and subdued them, as he afterwards was sent by him, when they rebelled against him, and were delivered out of his hand:
and into the hand of the Philistines:
as they were in and before the times of Samson, ( Judges 13:1 )
and into the hand of the king of Moab;
as in the times of Ehud, ( Judges 3:14 Judges 3:15 ) , the exact order of these things is not observed:
and they fought against them;
the king of Moab, Sisera, and the Philistines, and overcame them, and so they fell into their hands.
