Show me the verse. Show me the verse that includes khazaq and the unbetrothed damsel.
You already saw the sole occurrence of “khazaq” and I said no more than that. Are you asking for the scriptures to micromanage the rest or can you presume that even human judges can figure the rest out? Omission does not mean absence of jurisprudence.
Incidentally, getting back to the Ten Commandments (a law so stringent that no human can keep it—the Bible says that only with the Holy Spirit and faith it’d be possible to keep it), other verses in the rest of the Bible proscribe death for even breaking one of those commandments (Romans 6:23; James 2:10). The death penalty becomes more encompassing thereby.
