Isaiah 47:6

47:6 I was wroth with my people, I have polluted mine inheritance, and given them into thine hand: thou didst shew them no mercy; upon the ancient hast thou very heavily laid thy yoke.

Jeremiah 6:23

6:23 They shall lay hold on bow and spear; they [are] cruel, and have no mercy; their voice roareth like the sea; and they ride upon horses, set in array as men for war against thee, O daughter of Zion.
