'Flock' in the Bible

Now the priest of Midian had seven daughters. They came and drew water, and filled the troughs to water their father's flock.

The shepherds came and drove them away; but Moses stood up and helped them, and watered their flock.

They said, "An Egyptian delivered us out of the hand of the shepherds, and moreover he drew water for us, and watered the flock."

Now Moses was keeping the flock of Jethro, his father-in-law, the priest of Midian, and he led the flock to the back of the wilderness, and came to God's mountain, to Horeb.
