Mattityahu 17:18-20

Orthodox Jewish Bible

¹⁸ And Rebbe, Melech HaMoshiach rebuked it, and the shed came out of him, and the bocher received his refuah that hour.

¹⁹ Then the talmidim came to Rebbe, Melech HaMoshiach in a yechidus (private meeting with the Rebbe), and said, Why were we not able to cast it out?

²⁰ And Rebbe, Melech HaMoshiach said to them, On account of your little emunah, for, omein, I say to you, if you have emunah as a mustard seed, you shall say to this mountain, Move from here, and it shall be moved; and nothing shall be impossible for you.
