Ezekiel 21:12

Cry, as one in great distress; nay, how unseemly soever it may appear, howl, that they may by this know what sorrows are coming on them, and how they, like wild beasts taken in the toils and girts, shall howl. For the devouring sword of Babylon shall certainly be upon all, high and low. Terrors; surrounding terrors, out of which no way to escape. The sword; that sword God will draw against them. Smite upon thy thigh, in token of thy sense of what they must suffer, and to presignify what their sorrows shall be, when they must express them by signs, because too great for words.
