Here is, I. Israel backsliding from God: They again did evil in his sight, forsook his service, and worshipped idols; for this was the sin which now most easily beset them, Jdg 4:1. See in this, 1. The strange strength of corruption, which hurries men into sin notwithstanding the most frequent experience of its fatal consequences. The bent to backslide is with great difficulty restrained. 2. The common ill effects of a long peace. The land had rest eighty years, which should have confirmed them in their religion; but, on the contrary, it made them secure and wanton, and indulgent of those lusts which the worship of the false gods was calculated for the gratification of. Thus the prosperity of fools destroys them. Jeshurun waxeth fat and kicketh. 3. The great loss which a people sustains by the death of good governors. The did evil, because Ehud was dead. So it may be read. He kept a strict eye upon them, restrained and punished every thing that looked towards idolatry, and kept them close to God's service. But, when he was gone, they revolted, fearing him more than God.
II. Israel oppressed by their enemies. When they forsook God, he forsook them; and then they became an easy prey to every spoiler. They alienated themselves from God as if he were none of theirs; and then God alienated them as none of his. Those that threw themselves out of God's service threw themselves out of his protection. What has my beloved to do in my house when she has thus played the harlot? Jer 11:15. He sold them into the hand of Jabin, Jdg 4:2. This Jabin reigned in Hazor, as another of the same name, and perhaps his ancestor, had done before him, whom Joshua routed and slew, and burnt his city, Jos 11:1, Jos 11:10. But it seems, in process of time, the city was rebuilt, the power regained, the loss retrieved, and, by degrees, the king of Hazor becomes able to tyrannize over Israel, who by sin had lost all their advantage against the Canaanites. This servitude was longer than either of the former, and much more grievous. Jabin, and his general Sisera, did mightily oppress Israel. That which aggravated the oppression was, 1. That this enemy was nearer to them than any of the former, in their borders, in their bowels, and by this means had the more opportunity to do them a mischief. 2. That they were the natives of the country, who bore an implacable enmity to them, for invading and dispossessing them, and when they had them in their power would be so much the more cruel and mischievous towards them in revenge of the old quarrel. 3. That these Canaanites had formerly been conquered and subdued by Israel, were of old sentenced to be their servants (Gen 9:25), and might now have been under their feet, and utterly incapable of giving them any disturbance, if their own slothfulness, cowardice, and unbelief, had not suffered them thus to get head. To be oppressed by those whom their fathers had conquered, and whom they themselves had foolishly spared, could not but be very grievous.
III. Israel returning to their God: They cried unto the Lord, when distress drove them to him, and they saw no other way of relief. Those that slight God in their prosperity will find themselves under a necessity of seeking him when they are in trouble.

And the children of Israel cried unto the Lord,.... Because of their hard bondage, and begged deliverance from it, being brought to a sense of their sins, and humbled for them:

for he had nine hundred chariots of iron; the same with the , chariots which carried scythes at the side of them, fastened to the orbs of the wheels (x), and were on both sides; and in some stood out ten cubits (y) which running furiously among the infantry, cut them to pieces in a terrible manner; of which Cyrus had in his army at first but an hundred, afterwards increased to three hundred (z); and yet here a petty prince of Canaan had nine hundred of them; and which Josephus (a) has increased, beyond all belief, to the number of three thousand; which struck great terror into the Israelites, and who therefore durst not attempt to shake off his yoke, but cried to the Lord for help:

and twenty years he mightily oppressed the children of Israel; as they increased their sins, and repeated their revolts, the Lord increased their oppressions, and continued them the longer; the first was only eight years, the next eighteen, and this twenty, and which was a very heavy one; the other being foreign princes that oppressed them, but this a Canaanitish king, an implacable enemy, and who doubtless used them the more severely for what they had done to his ancestors, killed his father or grandfather, burnt the city of Hazor, and destroyed the inhabitants of it in Joshua's time; and the servitude was the harder, and the more intolerable to the Israelites, that they were under a people whose land had been given them to possess, and whom they had expelled, and now were become subject to them.

Jabin king of Canaan--"Jabin," a royal title (see on Jos 11:1). The second Jabin built a new capital on the ruins of the old (Jos 11:10-11). The northern Canaanites had recovered from the effect of their disastrous overthrow in the time of Joshua, and now triumphed in their turn over Israel. This was the severest oppression to which Israel had been subjected. But it fell heaviest on the tribes in the north, and it was not till after a grinding servitude of twenty years that they were awakened to view it as the punishment of their sins and to seek deliverance from God.
