'Pouch' in the Bible

Then he took his staff in his hand, picked out for himself five smooth stones from the wadi, and he put them in his shepherd's bag, in the pouch. And with his sling in his hand, he approached the Philistine.

Should a man arise to pursue you and to seek your life, may the life of my lord be wrapped in the pouch of the living with Yahweh your God. But as for the life of your enemy, he will sling it from within the pocket of the sling!
