The prophet Elijah predicts to Ahab, as a punishment for his idolatry the coming of a drought and famine. During their continuance he is miraculously preserved by God, first of all at the brook Cherith, and then at the house of a widow at Zarephath (vv. 1-16), whose deceased son he calls to life again (1Ki 17:17-24).
1Ki 17:1
Elijah the Tishbite is introduced without the formula “The word of the Lord came to ...,” with which the appearance of the prophets is generally announced, proclaiming to king Ahab in the name of the Lord the punitive miracle of a drought that will last for years. This abrupt appearance of Elijah cannot be satisfactorily explained from the fact that we have not the real commencement of his history here; it is rather a part of the character of this mightiest of all the prophets, and indicates that in him the divine power of the Spirit appeared as it were personified, and his life and acts were the direct effluence of the higher power by which he was impelled. His origin is also uncertain. The epithet התּשׁבּי is generally derived from a place called Tishbeh, since, according to Tobit 1:2, there existed in Upper Galilee a Θίσβη ἐκ δεξιῶν Κυδίως, “on the right, i.e., to the south of Kydios,” probably Kedesh in the tribe of Naphtali, from which the elder Tobias was carried away captive, although this description of the place is omitted in the Hebrew version of the book of Tobit issued by Fagius and Münster, and in the Vulgate. And to this we must adhere, and as no other Thisbe occurs, must accept this Galilean town as the birthplace of Elijah; in which case the expression “of the settlers of Gilead” indicates that Elijah did not live in his birthplace, but dwelt as a foreigner in Gilead. For תּושׁב in itself by no means denotes a non-Israelite, but, like גּד, simply one who lived away from his home and tribe relations in the territory of a different tribe, without having been enrolled as a member of it, as is clearly shown by Lev 25:40, and still more clearly by Jdg 17:7, where a Levite who was born in Bethlehem is described as גּר in the tribe of Ephraim.
The expression “as truly as Jehovah the God of Israel liveth, before whom I stand (i.e., whom I serve; see at 1Ki 1:2), there shall not fall dew and rain these years, except at my word,” was a special application of the threats of the law in Deu 11:16-17; Deu 28:23-24, and Lev 26:19, to the idolatrous kingdom. האלּה השּׁנים, “these (ensuing) years,” does not fix any definite terminus. In דברי לפי there is involved an emphatic antithesis to others, and more especially to the prophets of Baal. “When I shall say this by divine authority and might, let others prate and lie as they may please” (Berleb. Bibel). Elijah thereby describes himself as one into whose power the God of Israel has given up the idolatrous king and his people. In Jam 5:17-18, this act of Elijah is ascribed to the power of his prayers, since Elijah “was also a man such as we are,” inasmuch as the prophets received their power to work solely through faith and intercourse with God in prayer, and faith gives power to remove mountains.
