17 Behold, I will stir up against you the Medes, who do not regard silver, neither have they need of gold.
18 They shall break the bows of the young men; and they shall have no mercy on your children; nor shall their eyes spare thy children.
19 And Babylon, which is called glorious by the king of the Chaldeans, shall be as God overthrew Sodoma, and Gomorrha.
20 It shall never be inhabited, neither shall any enter into it for many generations: neither shall the Arabians pass through it; nor shall shepherds at all rest in it.
