ISA 28:17

17 I will test you [people of Jerusalem] to find out if you will act justly and righteously [like] [MET] someone uses a plumb line [to determine if a wall is straight and vertical]. But because your agreement [with Egypt] to protect you [was made by leaders] lying to each other and deceiving each other, you will be defeated and taken away [from your country] by [an army that will come against you like] [MET] a flood.
