'Reward' in the Bible

Wicked people earn deceitful wages, but one who sows righteousness reaps a sure reward.

He who has pity on the poor lends to Yahweh; he will reward him.

so you shall know wisdom to be to your soul; if you have found it, then there will be a reward, your hope will not be cut off.

for there will be no reward to the evil man; and the lamp of the wicked shall be snuffed out.

for you will heap coals of fire on his head, and Yahweh will reward you.
