'Reward' in the Bible

Rejoice, and be exceedingly glad, for great is your reward in heaven. For that is how they persecuted the prophets who were before you.

For if you love those who love you, what reward do you have? Don't even the tax collectors do the same?

"Be careful that you don't do your charitable giving before men, to be seen by them, or else you have no reward from your Father who is in heaven.

Therefore when you do merciful deeds, don't sound a trumpet before yourself, as the hypocrites do in the synagogues and in the streets, that they may get glory from men. Most certainly I tell you, they have received their reward.

so that your merciful deeds may be in secret, then your Father who sees in secret will reward you openly.

"When you pray, you shall not be as the hypocrites, for they love to stand and pray in the synagogues and in the corners of the streets, that they may be seen by men. Most certainly, I tell you, they have received their reward.

But you, when you pray, enter into your inner room, and having shut your door, pray to your Father who is in secret, and your Father who sees in secret will reward you openly.

"Moreover when you fast, don't be like the hypocrites, with sad faces. For they disfigure their faces, that they may be seen by men to be fasting. Most certainly I tell you, they have received their reward.

so that you are not seen by men to be fasting, but by your Father who is in secret, and your Father, who sees in secret, will reward you.

He who receives a prophet in the name of a prophet will receive a prophet's reward. He who receives a righteous man in the name of a righteous man will receive a righteous man's reward.

Whoever gives one of these little ones just a cup of cold water to drink in the name of a disciple, most certainly I tell you he will in no way lose his reward."
