'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.

For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward:

Cursed be he that taketh reward to slay an innocent person. And all the people shall say, Amen.

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 whet my glittering sword, and mine hand take hold on judgment; I will render vengeance to mine enemies, and will reward them that hate me.
