Passage
And a man that committeth adultery with a man's wife, who committeth adultery with his neighbour's wife, the adulterer and the adulteress shall certainly be put to death.
And a man that committeth adultery with a man's wife, who committeth adultery with his neighbour's wife, the adulterer and the adulteress shall certainly be put to death.
Leviticus 20:8 And ye shall observe my statutes, and do them: I am Jehovah who hallow you.
Leviticus 20:9 Whatever man revileth his father and his mother shall certainly be put to death: he hath reviled his father and his mother; his blood is upon him.
Leviticus 20:10 And a man that committeth adultery with a man's wife, who committeth adultery with his neighbour's wife, the adulterer and the adulteress shall certainly be put to death.
Leviticus 20:11 And a man that lieth with his father's wife hath uncovered his father's nakedness: both of them shall certainly be put to death; their blood is upon them.
Leviticus 20:12 And if a man lie with his daughter-in-law, both of them shall certainly be put to death: they have wrought confusion; their blood is upon them.
The verse centers on "committeth", "adultery", "man's", "wife", and "neighbour's". It is saying that the verse draws attention to "committeth" and "adultery", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "Whatever man revileth his father and his..." into verse 11's "And a man that lieth with his...", so "committeth" and "adultery" belong inside that flow. In Leviticus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "committeth" and "adultery" with trust shaped by these words, not by a vague optimism outside the passage.
