Be careful that you don’t practice your religion in front of people to draw their attention. If you do, you will have no reward from your Father who is in heaven.
Whenever you give to the poor, don’t blow your trumpet as the hypocrites do in the synagogues and in the streets so that they may get praise from people. I assure you, that’s the only reward they’ll get. But when you give to the poor, don’t let your left hand know what your right hand is doing so that you may give to the poor in secret. Your Father who sees what you do in secret will reward you.
When you pray, don’t be like hypocrites. They love to pray standing in the synagogues and on the street corners so that people will see them. I assure you, that’s the only reward they’ll get. But when you pray, go to your room, shut the door, and pray to your Father who is present in that secret place. Your Father who sees what you do in secret will reward you.

[Προσέχετε [δὲ] τὴν δικαιοσύνην ὑμῶν μὴ ποιεῖν ἔμπροσθεν τῶν ἀνθρώπων πρὸς τὸ θεαθῆναι αὐτοῖς· εἰ δὲ μή γε, μισθὸν οὐκ ἔχετε παρὰ τῷ πατρὶ ὑμῶν τῷ ἐν τοῖς οὐρανοῖς.
Ὅταν οὖν ποιῇς ἐλεημοσύνην, μὴ σαλπίσῃς ἔμπροσθέν σου, ὥσπερ οἱ ὑποκριταὶ ποιοῦσιν ἐν ταῖς συναγωγαῖς καὶ ἐν ταῖς ῥύμαις, ὅπως δοξασθῶσιν ὑπὸ τῶν ἀνθρώπων· ἀμὴν λέγω ὑμῖν, ἀπέχουσιν τὸν μισθὸν αὐτῶν. σοῦ δὲ ποιοῦντος ἐλεημοσύνην μὴ γνώτω ἡ ἀριστερά σου τί ποιεῖ ἡ δεξιά σου, ὅπως ᾖ σου ἡ ἐλεημοσύνη ἐν τῷ κρυπτῷ· καὶ ὁ πατήρ σου ὁ βλέπων ἐν τῷ κρυπτῷ ἀποδώσει σοι.
Καὶ ὅταν προσεύχησθε, οὐκ ἔσεσθε ὡς οἱ ὑποκριταί, ὅτι φιλοῦσιν ἐν ταῖς συναγωγαῖς καὶ ἐν ταῖς γωνίαις τῶν πλατειῶν ἑστῶτες προσεύχεσθαι, ὅπως φανῶσιν τοῖς ἀνθρώποις· ἀμὴν λέγω ὑμῖν, ἀπέχουσιν τὸν μισθὸν αὐτῶν. σὺ δὲ ὅταν προσεύχῃ, εἴσελθε εἰς τὸ ταμεῖόν σου καὶ κλείσας τὴν θύραν σου πρόσευξαι τῷ πατρί σου τῷ ἐν τῷ κρυπτῷ· καὶ ὁ πατήρ σου ὁ βλέπων ἐν τῷ κρυπτῷ ἀποδώσει σοι.]

(Source (Greek)). Alternate translations:

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. But when thou doest alms, let not thy left hand know what thy right hand doeth: 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.
[KJV (1611)]

Be careful not to parade your good deeds before men to attract their notice; by doing this you will lose all reward from your Father in heaven.
So when you give alms, do not have it trumpeted before you; this is what the hypocrites do in the synagogues and in the streets to win men's admiration. I tell you solemnly, they have had their reward. But when you give alms, your left hand must not know what your right is doing; your almsgiving must be secret, and your Father who sees all that is done in secret will reward you.
And when you pray, do not imitate the hypocrites: they love to say their prayers standing up in the synagogues and at the street corners for people to see them; I tell you solemnly, they have had their reward. But when you pray, go to your private room and, when you have shut your door, pray to your Father who is in that secret place, and your Father who sees all that is done in secret will reward you.
[JB (1966)]

Make certain you do not perform your religious duties in public so that people will see what you do. If you do these things publicly, you will not have any reward from your Father in heaven.
So when you give something to a needy person, do not make a big show of it, as the hypocrites do in the houses of worship and on the streets. They do it so that people will praise them. I assure you, they have already been paid in full. But when you help a needy person, do it in such a way that even your closest friend will not know about it. Then it will be a private matter. And your Father, who sees what you do in private, will reward you.
When you pray, do not be like the hypocrites! They love to stand up and pray in the houses of worship and on the street corners, so that everyone will see them.

And your Father, who sees what you do in private, will reward you.

[NJB (1985)]

So when you give to the needy, do not announce it with trumpets, as the hypocrites do in the synagogues and on the streets, to be honored by others.

Then your Father, who sees what is done in secret, will reward you.
