Levítico 20:10

Y el hombre que adulterare con la mujer de otro, el que cometiere adulterio con la mujer de su prójimo, indefectiblemente se hará morir al adúltero y á la adúltera.

¶ And the man that committeth adultery with another man’s wife, even he that committeth adultery with his neighbour’s wife, the adulterer and the adulteress shall surely be put to death.
