John Gill Bible Commentary

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, Jer 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, Kg2 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 Jdg 5:25. (n) Ut supra. (Antiqu. l. 5. c. 5. sect. 1.)
