The central thought of Micah is that Jehovah reproved Israel (the entire nation, including Judah) of her evils and promised her that He would save and gather her remnant for the restoration (Matt. 19:28) in the millennium (Rev. 20:4-7a).
A shortened form of Micaiah, meaning Who is like Jah? The longer form of the prophet’s name is found in the Hebrew text of Jer. 26:18.
