John Wesley on 2 Kings 3:11

Is there not, &c. - This he should have asked before, when they first undertook the expedition, as he did in a like case, 1Kings 22:5, and for that neglect he now suffers; but better late than never: his affliction brings him to the remembrance of his former sin, and present duty. Poured water - Who was his servant; this being one office of a servant: and this office was the more necessary among the Israelites, because of the frequent washings which their law required. Probably it was by a special direction from God, that Elisha followed them, unasked, unobserved. Thus does God prevent us with the blessings of his goodness; and provide for those who provide not for themselves.
