'Reward' in the Bible

Be glad in that day, and be lifted up for joy, for your reward in heaven will be great: for their fathers did these same things to the prophets.

But be loving to those who are against you and do them good, and give them your money, not giving up hope, and your reward will be great and you will be the sons of the Most High: for he is kind to evil men, and to those who have hard hearts.

And keep in that same house, taking what food and drink they give you: for the worker has a right to his reward. Do not go from house to house.

And he said to the master of the house, When you give a feast, do not send for your friends and your brothers and your family or your neighbours who have wealth, for they may give a feast for you, and so you will get a reward.

And you will have a blessing, because they will not be able to give you any payment, and you will get your reward when the upright come back from the dead.

But those to whom is given the reward of the world to come, and to come back from the dead, have no wives, and are not married;

And with reason; for we have the right reward of our acts, but this man has done nothing wrong.
