These words could be joined together and translated as “a homeless wanderer,” which means "a person who roams because he does not have a home."

This can be translated with an active verb. "I will take vengeance on him seven times" or "I will punish that person seven times as severely as I am punishing you." (UDB) (See: rc://en/ta/man/translate/figs-activepassive)

would not attack him

"would not kill Cain"
