'Shepherds' in the Bible

And there were shepherds in the same region, living out of doors and keeping watch, guarding over their flock by night.

And it happened that when the angels had departed from them into heaven, the shepherds began to say to one another, "Let us go now to Bethlehem and see this thing that has happened, which the Lord has revealed to us!"

And all who heard [it] were astonished concerning what had been said to them by the shepherds.

And the shepherds returned, glorifying and praising God for all that they had heard and seen, just as it had been told to them.

Who ever serves as a soldier at his own expense? Who plants a vineyard and does not eat the fruit of it? Who shepherds a flock and does not drink from the milk of the flock?
