Exodus 21:26-27

21:26 “If a man strikes the eye of his male servant or his female servant so that he destroys it, he will let the servant go free as compensation for the eye. 21:27 If he knocks out the tooth of his male servant or his female servant, he will let the servant go free as compensation for the tooth.

Deuteronomy 19:21

19:21 You must not show pity; the principle will be a life for a life, an eye for an eye, a tooth for a tooth, a hand for a hand, and a foot for a foot.

Proverbs 29:19

29:19 A servant cannot be corrected by words,

for although he understands, there is no answer.

Isaiah 58:3-4

58:3 They lament, ‘Why don’t you notice when we fast?

Why don’t you pay attention when we humble ourselves?’

Look, at the same time you fast, you satisfy your selfish desires,

you oppress your workers.

58:4 Look, your fasting is accompanied by arguments, brawls,

and fistfights.

Do not fast as you do today,

trying to make your voice heard in heaven.
