'Bruising' 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.

Night and day he was constantly screaming and shrieking among the tombs and on the mountains, and cutting himself with [sharp] stones.

So I looked, and behold, an ashen (pale greenish gray) horse [like a corpse, representing death and pestilence]; and its rider’s name was Death; and Hades (the realm of the dead) was following with him. They were given authority and power over a fourth part of the earth, to kill with the sword and with famine and with plague (pestilence, disease) and by the wild beasts of the earth.
