'Reward' in the Bible

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

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

Take heed that ye do not your alms before men, to be seen of them: otherwise ye have no reward of your Father which is in heaven.

Therefore when thou doest thine alms, do not sound 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 their reward.

That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly.

And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.

But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.

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

That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly.

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.

For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.
