(And a sword will go through your heart;) so that the secret thoughts of men may come to light.

And they will be put to death with the sword, and will be taken as prisoners into all the nations; and Jerusalem will be crushed under the feet of the Gentiles, till the times of the Gentiles are complete.

And he said to them, But now, he who has a money-bag, or a bag for food, let him take it: and he who has not, let him give his coat for money and get a sword.
