Mattityahu 23:3-5

Orthodox Jewish Bible

³ Therefore, everything whatever they may tell you, be frum and be shomer, but according to their ma’asim (works) do not be shomer, for they do not practice what they preach.

⁴ And they tie up heavy [extra-Biblical, Mt 4:4; 15:3,6-9; 22:29] loads, hard to bear, and they place them upon the shoulders of men, but they, with so much as a finger, are not willing to lift the oppressive burdens.

⁵ And all their maasim hamitzvot (works of the commandments) they do in order to be seen by Bnei Adam, for they broaden their tefillin and lengthen their tzitziyot
