The teachers of the law and the Pharisees sit in Moses’ seat. So you must be careful to do everything they tell you. But do not do what they do, for they do not practice what they preach. They tie up heavy, cumbersome loads and put them on other people’s shoulders, but they themselves are not willing to lift a finger to move them.
Everything they do is done for people to see: They make their phylacteries wide and the tassels on their garments long; they love the place of honor at banquets and the most important seats in the synagogues; they love to be greeted with respect in the marketplaces and to be called “Rabbi” by others.

Alternate translations:

The scribes and the Pharisees sit in Moses' seat: All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not. For they bind heavy burdens and grievous to be borne, and lay them on men's shoulders; but they themselves will not move them with one of their fingers. But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments, and love the uppermost rooms at feasts, and the chief seats in the synagogues, and greetings in the markets, and to be called of men, Rabbi, Rabbi.
[KJV (1611)]

The scribes and the Pharisees occupy the chair of Moses. You must therefore do what they tell you and listen to what they say; but do not be guided by what they do: since they do not practice what they preach. They tie up heavy burdens and lay them on men's shoulders, but will they lift a finger to move them? Not they! Everything they do is done to attract attention, like wearing broader phylacteries and longer tassels, like wanting to take the place of honour at banquets and the front seats in the synagogues, being greeted obsequiously in the market squares and having people call them Rabbi.
[JB (1966)]

The teachers of the Law and the Pharisees are the authorized interpreters of Moses' Law. So you must obey and follow everything they tell you to do; do not, however, imitate their actions, because they don't practice what they preach. They tie onto people's backs loads that are heavy and hard to carry, yet they aren't willing even to lift a finger to help them carry those loads. They do everything so that people will see them. Look at the straps with scripture verses on them which they wear on their foreheads and arms, and notice how large they are! Notice also how long are the tassels on their cloaks! They love the best places at feasts and the reserved seats in the synagogues; they love to be greeted with respect in the marketplaces and to have people call them "Teacher."
[GNT (1976)]

The scribes and the Pharisees occupy the chair of Moses. You must therefore do and observe what they tell you; but do not be guided by what they do, since they do not practice what they preach. They tie up heavy burdens and lay them on people's shoulders, but will they lift a finger to move them? Not they! Everything they do is done to attract attention, like wearing broader headbands and longer tassels, like wanting to take the place of honour at banquets and the front seats in the synagogues, being greeted respectfully in the market squares and having people call them Rabbi.
[NJB (1985)]

The legal experts and the Pharisees sit on Moses’ seat. Therefore, you must take care to do everything they say. But don’t do what they do. For they tie together heavy packs that are impossible to carry. They put them on the shoulders of others, but are unwilling to lift a finger to move them. Everything they do, they do to be noticed by others. They make extra-wide prayer bands for their arms and long tassels for their clothes. They love to sit in places of honor at banquets and in the synagogues. They love to be greeted with honor in the markets and to be addressed as "Rabbi."
[CEB (2011)]

The scribes and the Pharisees sit on Moses’s seat; therefore, do whatever they teach you and follow it, but do not do as they do, for they do not practice what they teach. They tie up heavy burdens, hard to bear, and lay them on the shoulders of others, but they themselves are unwilling to lift a finger to move them. They do all their deeds to be seen by others, for they make their phylacteries broad and their fringes long. They love to have the place of honor at banquets and the best seats in the synagogues 7 and to be greeted with respect in the marketplaces and to have people call them rabbi.
