The Lord Will Rule Forever and Ever

This song that sung at the sea mentioned something. It's subtle, but it mentions something that doesn't happen until much later in the biblical story.

And theologically, Mount Zion takes the place of Mount Sinai in Israel; Yahweh will rule not through the kings, but forever and ever.
