And the word of the Lord came to him,.... The word of prophecy, as the Targum; this shows that by word, in the former verse, he means the word of the Lord by him:
saying; as follows.

the word of the Lord came unto him, saying, Get thee hence, and turn thee eastward, &c.--At first the king may have spurned the prediction as the utterance of a vain enthusiast; but when he found the drought did last and increase in severity, he sought Elijah, who, as it was necessary that he should be far removed from either the violence or the importunities of the king, was divinely directed to repair to a place of retreat, perhaps a cave on "the brook Cherith, that is, before [east of] Jordan." Tradition points it out in a small winter torrent, a little below the ford at Beth-shan.

After the announcement of this judgment, Elijah had to hide himself, by the command of God, until the period of punishment came to an end, not so much that he might be safe from the wrath and pursuit of Ahab and Jezebel, as to preclude all earnest entreaties to remove the punishment. "For inasmuch as the prophet had said that the rain would come at his word, how would they have urged him to order it to come!" (Seb. Schm.) He was to turn קדמה, eastward, i.e., from Samaria, where he had no doubt proclaimed the divine judgment to Ahab, to the Jordan, and to hide himself at the brook Cherith, which is in front of the Jordan. The brook Cherith was in any case a brook emptying itself into the Jordan; but whether upon the eastern or the western side of that river, the ambiguity of על־פּני, which means both "to the east of" (Genesis 25:18) and also "in the face of," i.e., before or towards (Genesis 16:12; Genesis 18:16), it is impossible to determine with certainty. That it must signify "to the east of the Jordan" here, does not follow from קדמה with anything like the certainty that Thenius supposes. An ancient tradition places the Cherith on this side of the Jordan, and identifies it with the spring Phasaelis, which takes its rise in the slope of the mountains into the Jordan valley above the city of Phasaelis, and empties itself into the Jordan (cf. Ges. thes. p. 719, and V. de Velde, Reise, ii. pp. 273-4); whereas Eusebius, in the Onom. s.v. Chorat (Chorra'), places it on the other side of the Jordan, and Thenius thinks of the apparently deep Wady Rajib or Ajlun. All that can be affirmed with certainty is, that neither the brook Kanah (Joshua 16:8; Joshua 17:9), which flows into the Mediterranean, nor the Wady Kelt near Jericho, which Robinson (Pal. ii. p. 288) suggests, can possibly come into consideration: the latter for the simple reason, that the locality in the neighbourhood of Jericho was unsuitable for a hiding-place. Elijah was to drink of this brook, and the ravens by divine command were to provide him with bread and meat, which they brought him, according to 1-Kings 17:6, both morning and evening. It is now generally admitted that הערבים does not mean either Arabs or Orebites (the inhabitants of an imaginary city named Oreb), but ravens. Through this miracle, which unbelievers reject, because they do not acknowledge a living God, by whom, as the Creator and Lord of all creatures, even the voracious ravens are made subservient to His plans of salvation, Elijah was not only cut off from intercourse with men, who might have betrayed his place of abode to the king, but was mightily strengthened himself, through the confidence inspired in the almighty assistance of his God, for his approaching contests with the worshippers of idols, and for the privations and sufferings which awaited him in the fulfilment of his vocation.
