'Sheepfold' in the Bible

Then he chose his servant David, whom he took from the sheepfold.

"Jacob, how I will surely gather all of you! How I will gather the survivors of Israel! I will gather them together like sheep in a pen, like the flock in the midst of the sheepfold. There will be a great commotion because of all the people.

Even though the fig tree does not blossom, and there are no grapes on the vines; even if the olive harvest fails, and the fields produce nothing edible; even if the flock is snatched from the sheepfold, and there is no herd in the stalls

"Truly, I tell all of you emphatically, the person who doesn't enter the sheepfold through the gate, but climbs in by some other way, is a thief and a bandit.
