The fish gate - The gate through which fish from the Jordan and the Sea of Galilee entered Jerusalem; a gate in the north wall, a little to the east of the modern Damascus gate.
Locks - The word used (here and in Nehemiah 3:6, Nehemiah 3:13-15) is thought to mean rather a “cross-bar” than a lock, while that translated “bars” is regarded as denoting the “hooks” or “catches” which held the cross-bar at its two ends.
