'Shepherd's' in the Bible

He took his staff in his hand and chose for himself five smooth stones from the brook and put them in the pouch in his shepherd's bag. He approached the Philistine with his sling in his hand.

If you don't know, most beautiful of women, go out after the flock and graze your young goats beside the shepherd's tents.

My house has been plucked up and vanishes from me like a shepherd's tent; like a weaver, I've taken account of my life, and he cuts me off from the loom day and night you make an end of me.
