bay
denotes the estuary of the Dead Sea at the mouth of the Jordan (Joshua 15:5; 18:19), also the southern extremity of the same sea (15:2)
The same Hebrew word is translated “tongue” in Isaiah 11:15, where it is used with reference to the forked mouths of the Nile.
Bay in Zechariah 6:3, 7 denotes the color of horses in the King James Version, but the original Hebrew means strong, and is here used rather to describe the horses as strong or courageous, fleet or spirited.
