Ith'iel (Heb. lthiel', אַיתַיאֵל, for אַתַּי אֵל, God with me, or, according to Furst, the property of God; Sept. Αἰθιήλ,Vurlg. Etheel; but in Pr 31:1, both translate οἱ πιστεύοντες θεῷ, cum quo est Deus and Deo secum morante), the name of two men.
1. A person mentioned along with Ucal in Pr 30:1, apparently as one to whom the "words of Agur's prophecy" had been addressed. B.C. perhaps cir. 990. SEE AGUR. Gesenius (Thesaur. Heb. p. 88) thinks that Ithiel and Ucal were the children or disciples of Agur, to whom he inscribed his aphorisms; others regard both words as appellatives, and render the whole clause as follows: "Thus spake the man: I have toiled for God, I have toiled for God, and have ceased" (see Stuart's Comment. ad loc.).
2. The son of Jesaiah and father of Maaseiah, a Benjamite, one of whose posterity returned with a party from Babylon (Ne 11:7). B.C. long ante 536.
