'Bag' in the Bible

And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd's bag which he had, even in a scrip; and his sling was in his hand: and he drew near to the Philistine.

And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.

When someone sets out to chase you and to take your life, the life of my lord will be wrapped securely in the bag of the living by the Lord your God. But he will sling away the lives of your enemies from the sling's pocket!
