Mattityahu 6:4-6

Orthodox Jewish Bible

⁴ so that your tzedakah may be nistar (hidden, in secret), and your Av HaRoeh b’seter (Father, the One seeing in secret) [His] sachar (reward) will give you.

⁵ And whenever you daven (pray), do not be as the tzevuim (hypocrites); for they love to stand and daven in the shuls and on the street corners so that they may be seen by an audience. Omein, truly I say to you, they have their sachar.

⁶ But you, whenever you daven, enter into the secret place, your secret cheder, and, having shut your door, offer tefillos to your Av Asher bSeter (Father Who is in Secret), and your Av haRoeh b’seter (Father the One seeing in secret) [His] sachar will give you.
