We shall perish by guile just as we slew.

All they that take the sword, shall perish with the sword

But there shall not an hair of your head perish.

For the LORD knoweth the way of the righteous: but the way of the ungodly shall perish.

And one who is just of his own free will shall not lack for happiness; and he will never come to utter ruin.

Rome shall perish - write that word / In the blood that she has spilt.
