Mattityahu 6:6-8

Orthodox Jewish Bible

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.

⁷ But when you daven, do not babble on and on maarich (extended, long winded) and vacuously and without kavvanah (heartfelt direction, intention) like the Goyim. For the Goyim think that in their verbosity their techinnah will be heard.

⁸ Therefore, nisht azoi (not so)! Be different, for your Av has daas (knowledge) of what things you have need before you ask Him.
