From Tishbe in the tribe of Naphtali, where Elijah was born, 1Ki 17:1. It is mentioned in one of the apocryphal books.
Elijah the prophet was thus named (1Ki 17:1; 21:17,28, etc.). In 1Ki 17:1 the word rendered "inhabitants" is in the original the same as that rendered "Tishbite," hence that verse may be read as in the LXX., "Elijah the Tishbite of Tishbi in Gilead." Some interpret this word as meaning "stranger," and read the verse, "Elijah the stranger from among the strangers in Gilead." This designation is probably given to the prophet as denoting that his birthplace was Tishbi, a place in Upper Galilee (mentioned in the apocryphal book of Tobit), from which for some reason he migrated into Gilead. Josephus, the Jewish historian (Ant. 8:13, 2), however, supposes that Tishbi was some place in the land of Gilead. It has been identified by some with el-Ishtib, a some place 22 miles due south of the Sea of Galilee, among the mountains of Gilead.
Derived from Thisbe in upper Galilee to the S. of Kedesh in Naphtali; see the apocryphal Tob 1:2. Elijah was born here, but settled in Gilead as a stranger. See 1Ki 17:1, "who was of the settlers (mitoshabey) of Gilead." Kurtz less probably (see Keil on 1Ki 17:1) supposes Tishbite to be the Tisieh mentioned by Robinson (Pal. iii. 153) in Gilead S. of Bostra. Paine identifies Tishbite with Listib overhung by the monastery Mar Ilyas (Elijah).
