'Folds' in the Bible

Issacher is a strong ass, Crouching between the two folds;

And they come nigh unto him, and say, 'Folds for the flock we build for our cattle here, and cities for our infants;

build for yourselves cities for your infants, and folds for your flock, and that which is going out from your mouth do ye.'

and he cometh in unto folds of the flock, on the way, and there is a cave, and Saul goeth in to cover his feet; and David and his men in the sides of the cave are abiding.

I take not from thy house a bullock, From thy folds he goats.

And He fixeth on David His servant, And taketh him from the folds of a flock,

And the sea-coast hath been habitations, Cottages for shepherds, and folds for a flock.
