Proverbs 25:20

These people are all cruel.

If someone steals a coat on a cold day, then that thief is very cruel. If someone pours acid on soap, that person is cruel. He spoils the soap. Now, nobody can use the soap.

A singer might not seem cruel. But this singer is cruel also.

Someone is sad. But this singer is happy. The singer does not think about the sad man. And the singer does not try to help the sad man. Instead, the singer continues to sing. And this upsets the sad man. So the sad man becomes sadder. And the singer does not even realise that his actions are cruel.

v21 If your enemy is hungry, then give food to him.

If your enemy needs a drink, then give water to him.

v22 He will feel as if burning coal is on his head.

But God will reward you.
