LDS First Token of the Melchizedek Priesthood:

“‘We agree that our bodies be cut asunder in the midst and all our bowels gush out.’ … As the last words are spoken the hands are dropped till the thumbs are in the center of the stomach and drawn swiftly across the stomach to the hips, and then dropped to the sides.”

LDS Endowment Ceremony, circa 1931; see also Abanes, One Nation Under Gods (New York, NY: Four Walls Eight Windows, 2003), 38.

Masonic Third or Master Mason’s Degree:

“[I am bound] under no less penalty than to have my body severed in two in the midst, and divided to the north and south, my bowels burnt to ashes in the center … The Penal Sign is given by putting the right hand to the left side of the bowels, the hand open, with the thumb next to the belly, and drawing it across the belly, and letting it fall; this is done tolerably quick. This alludes to the penalty of the obligation: ‘Having my body severed in twain, etc.’”
