'Pocket' 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 the shepherd's bag that he had, into the pocket; and his sling was in his hand. And he drew near to the Philistine.

If anyone should arise to pursue you and seek your life, may the life of your majesty be bound up with the LORD your God in a bundle of the living, and may he sling out the lives of your enemies from the pocket of a sling.
