Mithnite

Mith'nite (Heb. Mithni', מַתנַי, patronymic or gentile apparently from מֶתֶן, Me'then, firmness; Sept. Μαθθανί v.r. Βαιθανί, Vulg. Mathanites, as if from מִתָּן, Mat'tan), an epithet of Joshaphat, one of David's body-guard (1Ch 11:43); either from his ancestor or native place, of neither of which, however, is there any other mention, or further means of determination.
