'Reward' in the Bible

Rejoice in that day, and leap for joy, for behold, your reward is great in heaven, for their fathers did the same thing to the prophets.

But love your enemies, and do good, and lend, expecting nothing back; and your reward will be great, and you will be children of the Most High; for he is kind toward the unthankful and evil.

And we indeed justly, for we receive the due reward for our deeds, but this man has done nothing wrong."
