The sons of Hassenaah built the Fish Gate. They laid its beams and hung its doors, its bolts, and its bars. Bible see other translations

“bars.” The “bars” were strong wooden beams that were placed behind the doors so they could not be opened and could withstand pounding from the outside without giving way. Those bars were the origin of the shout “Bar the doors!” when an enemy would approach.
