A Yahwistic equivalent of the Gentile-English "Jesus Christ" or the Messianic Jewish "Yeshua HaMashiach".
Old Testament scholars often refer to the religion of the Hebrew Bible as "Yahwism", because Yahweh is the center of this religion, and the name "Yahweh" is used throughout.

Hence the Yahwistic "Yahshua HaMashiach" versus the Jewish "Yeshua HaMashiach".
