'Reward' in the Bible

Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets that were before you.

For if ye love them that love you, what reward have ye? do not even the publicans the same?

Take heed that ye do not your righteousness before men, to be seen of them: else ye have no reward with your Father who is in heaven.

When therefore thou doest alms, sound not a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, They have received their reward.

And when ye pray, ye 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 of men. Verily I say unto you, They have received their reward.

Moreover when ye fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may be seen of men to fast. Verily I say unto you, They have received their reward.

He that receiveth a prophet in the name of a prophet shall receive a prophet's reward: and he that receiveth a righteous man in the name of a righteous man shall receive a righteous man's reward.

And whosoever shall give to drink unto one of these little ones a cup of cold water only, in the name of a disciple, verily I say unto you he shall in no wise lose his reward.
