'Defence' in the Bible

only rebel not against Jehovah; and fear not the people of the land; for they shall be our food. Their defence is departed from them, and Jehovah is with us: fear them not.

and a third part shall be at the gate of Sur; and a third part at the gate behind the couriers; and ye shall keep the watch of the house for a defence.

And Rehoboam dwelt in Jerusalem, and built cities for defence in Judah.

Hear now my defence, and hearken to the pleadings of my lips.

Incline thine ear to me, deliver me speedily; be a strong rock to me, a house of defence to save me.

For wisdom is a defence as money is a defence; but the excellency of knowledge is, that wisdom maketh them that possess it to live.
