DIBLAH (dĭb'lă). Occurs in Ezek.6.14; KJV has “Diblath.” A few Hebrew manuscripts have “Diblah.” It was a town about fifty miles (eighty-three km.) south of Hamath. In Ezekiel this place was the northern limit of God’s judgments that were to fall on Palestine for its odious idolatry.

International Standard Bible Encyclopedia (1915)

The name occurs only in Eze 6:14 (the King James Version "Diblath"), and the place has not been identified. If the reading is correct it may possibly be represented by Dibl, a village in Upper Galilee, South of Tibnin. But more likely it is a scribal error for Riblah.
