48:16, Multitude in the midst of the earth. The ArtsScroll Stone Edition Tanakh translates this verse as follows:

“‘May the angel who redeems me from all evil bless the lads, and may my name be declared upon them, and the names of my forefathers Abraham and Isaac, and may they [Ephraim and Manasseh] proliferate abundantly like fish within the land.’

Onkelos renders this verse as follows:

‘And like the fish of the sea may they multiply among the children of men on earth’ … The literal translation of VDS/dalet-gimel-hey [dagah] refers to procreation … [and] the word essentially denotes fish (The ArtScroll Bereishis/Genesis Commentary p. 2117, emphasis added).

What religious group on earth today has spread out across the face of the earth into all nations and has proliferated a message of Redemption pertaining to a Messenger of YHVH involving a cross-symbol resembling the ancient paleo-Hebrew letter tav and a fish symbol?
