Throughout the Bible, there are many analogies of sheep and their shepherds:

Moses was a shepherd for the Israelites, leading them through the wilderness for 40 years.
David was a shepherd before he became King of Israel.
Jesus described himself as "the Good Shepherd” in John 10, one who “lays down his life for his sheep."

We hear about sheep and shepherds in the Parable of the Lost Sheep, where the shepherd went after the one sheep who had strayed from the fold and did not stop looking until he found it. We read about God as our shepherd in Psalm 23 and throughout the book of Psalms:

"But he brought his people out like a flock; he led them like sheep through the wilderness." (Psalm 78:52)

"Come, let us bow down in worship, let us kneel before the Lord our Maker; for he is our God and we are the people of his pasture, the flock under his care." (Psalm 95:6-7)

"Know that the Lord is God. It is he who made us, and we are his; we are his people, the sheep of his pasture." (Psalm 100:3)
