Forewarned is forearmed.

From now on, it is our task to suspect each and everyone amongst us. Forewarned is forearmed. Take no risks and be alert to danger. That is all.

Be wary

Beware of, Had I wist.

Well warned to beware with whom he dar'd to dallie.

He who warned, uh, the— the British that they weren't going to be takin' away our arms, uh, by ringin' those bells and um makin' sure as he's riding his horse through town to send those warning shots and bells that, uh, we were going to be secure and we were going to be free, and we were going to be armed.

Hector. My word is simple. Arm and face the foe.

I warned them that the war was ahead of us, that it was prepared, and that they would save the honour of their people by deserting that war. But what I said then was not heard because of cannons.

It was anticipating self-defense.

History is a vast early warning system.

Foreknowledge is power.

Foresight is a virtue and averts many a misfortune.

Fear bespeaks of wisdom. Recognition of responsibility.

Arm yourself, my heart: the thing that you must do is fearful, yet inevitable.
