The Bible is quite clear on the punishment for adultery. Your people use god for hate and murder. Sad.
OT..Jews only....only exception today would be to stone you.
All are now under NT law..
"Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross" -- Col 2:14
"Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.For where a will is involved, the death of the one who made it must be established. For a will takes effect only at death, since it is not in force as long as the one who made it is alive.Therefore not even the first covenant was inaugurated without blood." -- Hebrews 9: 15 -18
