'Shepherd's' in the Bible

He took his stick in his hand and chose for himself five smooth stones from the brook, and put them in the shepherd’s bag which he had, even in his pouch, and his sling was in his hand; and he approached the Philistine.

“Like a shepherd’s tent my dwelling is pulled up and removed from me;As a weaver I rolled up my life.He cuts me off from the loom;From day until night You make an end of me.
