'Shield' in the Bible

O mountains of Gilboa, may there be no dew or rain on you, nor fields of grain offerings! For it was there that the shield of warriors was defiled; the shield of Saul lies neglected without oil.

My God is my rocky summit where I take shelter, my shield, the horn that saves me, my stronghold, my refuge, my savior. You save me from violence!

The one true God acts in a faithful manner; the Lord's promise is reliable; he is a shield to all who take shelter in him.

You give me your protective shield; your willingness to help enables me to prevail.
