'Sheepfold' in the Bible
Now therefore, thus shall you say to My servant David, Thus says the Lord of hosts: I took you from the sheepfold, from following the sheep, that you should be prince over My people Israel.
Wail, O Heshbon [in Moab, just south of Ammon], for Ai [in Ammon] is laid waste! Cry out, you daughter [villages] of Rabbah! Gird yourselves with sackcloth, lament, and run to and fro inside the [sheepfold] enclosures; for Milcom [the god-king] shall go into exile, together with his priests and his princes.
See, there comes up one like a lion from the jungles (the pride) of the Jordan against the strong habitation [of Babylon] and into the permanent pasturage and sheepfold; for in a twinkling I will drive him [Babylon] from there. And I will appoint over him the one whom I choose. For who is like Me? And who will challenge Me and prosecute Me for this proceeding? And what [earthly, national] shepherd can stand before Me and defy Me?
I assure you, most solemnly I tell you, he who does not enter by the door into the sheepfold, but climbs up some other way (elsewhere, from some other quarter) is a thief and a robber.
