The king of Israel said, Alas, &c. He did not cry to God for help, but only bewailed the straits into which they were fallen; which his own guilt made him imagine God had brought to pass for their destruction. Jehoshaphat said, Is there not here a prophet This he should have asked before, when they first undertook the expedition, as he did in a like case, (1 Kings 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. Here is Elisha, who poured water, &c. 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.
