'Reward' in the Bible

Be certain then that the Lord your God is not giving you this good land as a reward for your righteousness; for you are a stiff-necked people.

Cursed is he who for a reward puts to death one who has done no wrong. And let all the people say, So be it.

Punishment is mine and reward, at the time of the slipping of their feet: for the day of their downfall is near, sudden will be their fate.

If I make sharp my shining sword, and my hand is outstretched for judging, I will give punishment to those who are against me, and their right reward to my haters.
