'Reward' in the Bible

All that my eyes desired, I did not deny them. I did not refuse myself any pleasure, for I took pleasure in all my struggles. This was my reward for all my struggles.

I have seen that there is nothing better than for a person to enjoy his activities because that is his reward. For who can enable him to see what will happen after he dies?

Two are better than one because they have a good reward for their efforts.

Here is what I have seen to be good: it is appropriate to eat, drink, and experience good in all the labor one does under the sun during the few days of his life God has given him, because that is his reward.

God has also given riches and wealth to every man, and He has allowed him to enjoy them, take his reward, and rejoice in his labor. This is a gift of God,

For the living know that they will die, but the dead don’t know anything. There is no longer a reward for them because the memory of them is forgotten.
