Yahweh the king of the earth (Zech 14:9-14:9)

“Yahweh

Will become king

Over all the earth.

On that day,

Yahweh will be one.

His name will be one.”

On that glorious day, Yahweh, and Yahweh alone, would be king of the whole earth.  His name would be the only one, a true monotheistic statement about the end times.
