ISA 31:3

3 The soldiers of Egypt [that you people of Judah are relying on] are humans, not God! And their horses are only horses; they are not [powerful] spirits! So when Yahweh raises his fist to strike/punish the [soldiers of Egypt whom you thought would help you], he will also strike [you who thought that you would be helped], and you and they will stumble and fall down; all of you will die together.
