'Shepherd's' in the Bible

He took his staff in his hand, and chose for himself five smooth stones out of the brook, and put them in the shepherd's bag which he had, even in his wallet. His sling was in his hand; and he drew near to the Philistine.

My dwelling is removed, and is carried away from me like a shepherd's tent. I have rolled up, like a weaver, my life. He will cut me off from the loom. From day even to night you will make an end of me.
