'Wounding' in the Bible

Lamech said to his wives, "Adah and Zillah, hear my voice. You wives of Lamech, listen to my speech, for I have slain a man for wounding me, a young man for bruising me.

Then he found another man, and said, "Please strike me." The man struck him, smiting and wounding him.

Wounding blows cleanse away evil, and beatings purge the innermost parts.
