become one flesh

The Greek and Hebrew that is often translated into English as “(the two) shall become one flesh” is translated as “become just one” in Copainalá Zoque and San Mateo del Mar Huave or with existing idiomatic equivalents such as “become one blood” in Mitla Zapotec and “become the complement of each other’s spirit” in Tzeltal.
