She opened a bottle of milk - She gave more than he requested; and her friendship increased his confidence and security.

And he said unto her, give me, I pray thee, a little water to drink, for I am thirsty,.... Which might be occasioned by the heat of the battle, and by the heat of the day, and by heat in running; he asks for a little water, that being very desirable by persons athirst. Some think he did not ask for wine, because he knew the Kenites did not drink any, and so of course kept none in their tents; but though this was the custom of the Rechabites, who were the same with the Kenites, Jeremiah 35:8; yet it is very probable this custom had not yet obtained among them, since it was enjoined by Jonadab their father, who lived in the times of Jehu, 2 Kings 10:15,

and she opened a bottle of milk, and gave him to drink; which she did either out of courtesy, being a better liquor, or with design to throw him into a sleep, which milk inclines to, making heavy, as all the Jewish commentators observe; though Josephus (n) has no authority to say, as he does? that the milk she gave him was bad and corrupt:

and covered him: again, after he had taken a draught of milk, which it seems she poured into a dish with the cream on it, see Judges 5:25.

(n) Ut supra. (Antiqu. l. 5. c. 5. sect. 1.)

On his asking for water to drink, as he was thirsty (צמתּי, defective form for צמאתּי), she handed him milk from her bottle, and covered him up again. She gave him milk instead of water, as Deborah emphatically mentions in her song in Judges 5:25, no doubt merely for the purpose of giving to her guest a friendly and hospitable reception. When Josephus affirms, in his account of this event (Ant. v. 5, 4), that she gave him milk that was already spoiled (διεφθορὸς ἤδη), i.e., had turned sour, and R. Tanchum supposes that such milk intoxicated the weary man, these are merely later decorations of the simple fact, that have no historical worth whatever.

And he said unto her, Give me, I pray thee, a little water to drink; for I am thirsty. And she opened a bottle of milk, and gave him drink, and covered him.

4:19 A bottle of milk - As a signification of greater respect. Covered him - Upon pretence of hiding him.

19. she . gave him drink, and covered him-Sisera reckoned on this as a pledge of his safety, especially in the tent of a friendly sheik. This pledge was the strongest that could be sought or obtained, after he had partaken of refreshments, and been introduced in the inner or women's apartment.

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, Isa 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.
