'Shield' in the Bible

Mountains of Gilboa, let no dew or rain fall on you, and may none of your fields be filled with plenty, because in that place the shield of the valiant ones was defiled, the shield of Saul without an anointing with oil.

He is my God, my strong stone in him I will find my refuge my shield, the strength of my salvation, my high tower, my way of escape, and the one who is saving me. You will save me from violence.

He has equipped me with the shield that is your salvation, Your gentleness has made me great.
