'Wounding' in the Bible

Lamech said to his wives,“Adah and Zillah,Hear my voice;You wives of Lamech,Listen to what I say;For I have killed a man [merely] for wounding me,And a boy [only] for striking (bruising) me.

And when you sin against the brothers and sisters in this way and wound their weak conscience [by confusing them], you sin against Christ.
