Bay

Denotes the estuary of the Dead Sea at the mouth of the Jordan (Josh 15:5; Josh 18:19), also the southern extremity of the same sea (Josh 15:2). The same Hebrew word is rendered “tongue” in Isa 11:15, where it is used with reference to the forked mouths of the Nile.

Bay in Zech 6:3, Zech 6:7 denotes the colour of horses, but the original Hebrew means strong, and is here used rather to describe the horses as fleet or spirited.
