15 God routed Sisera - all those chariots, all those troops! - before Barak. Sisera jumped out of his chariot and ran. 16 Barak chased the chariots and troops all the way to Harosheth Haggoyim. Sisera's entire fighting force was killed - not one man left.

17 Meanwhile Sisera, running for his life, headed for the tent of Jael, wife of Heber the Kenite. Jabin king of Hazor and Heber the Kenite were on good terms with one another. 18 Jael stepped out to meet Sisera and said, "Come in, sir. Stay here with me. Don't be afraid." So he went with her into her tent. She covered him with a blanket. 19 He said to her, "Please, a little water. I'm thirsty." She opened a bottle of milk, gave him a drink, and then covered him up again. 20 He then said, "Stand at the tent flap. If anyone comes by and asks you, 'Is there anyone here?' tell him, 'No, not a soul.'" 21 Then while he was fast asleep from exhaustion, Jael wife of Heber took a tent peg and hammer, tiptoed toward him, and drove the tent peg through his temple and all the way into the ground. He convulsed and died.

Commentary on Judges 4:10-16.

(Read Judges 4:10-16.)

Siser's confidence was chiefly in his chariots. But if we have ground to hope that God goes before us, we may go on with courage and cheerfulness. Be not dismayed at the difficulties thou meetest with in resisting Satan, in serving God, or suffering for him; for is not the Lord gone before thee? Follow him then fully. Barak went down, though upon the plain the iron chariots would have advantage against him: he quitted the mountain in dependence on the Divine power; for in the Lord alone is the salvation of his people, Jeremiah 3:23. He was not deceived in his confidence. When God goes before us in our spiritual conflicts, we must bestir ourselves; and when, by his grace, he gives us some success against the enemies of our souls, we must improve it by watchfulness and resolution.

Commentary on Judges 4:17-24

(Read Judges 4:17-24)

Sisera's chariots had been his pride and his confidence. Thus are those disappointed who rest on the creature; like a broken reed, it not only breaks under them, but pierces them with many sorrows. The idol may quickly become a burden, Isaiah 46:1; what we were sick for, God can make us sick of. It is probable that Jael really intended kindness to Sisera; but by a Divine impulse she was afterwards led to consider him as the determined enemy of the Lord and of his people, and to destroy him. All our connexions with God's enemies must be broken off, if we would have the Lord for our God, and his people for our people. He that had thought to have destroyed Israel with his many iron chariots, is himself destroyed with one iron nail. Thus the weak things of the world confound the mighty. The Israelites would have prevented much mischief, if they had sooner destroyed the Canaanites, as God commanded and enabled them: but better be wise late, and buy wisdom by experience, than never be wise.
