Then Jesus said to the crowds and to his disciples, 2 “The scribes and the Pharisees sit on Moses’ seat, 3 so do and observe whatever they tell you, but not the works they do. For they preach, but do not practice.

Behold, you delight in truth in the inward being,

and you teach me wisdom in the secret heart.

They tie up heavy burdens, hard to bear, and lay them on people’s shoulders, but they themselves are not willing to move them with their finger

27 Religion that is pure and undefiled before God the Father is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world.

5 They do all their deeds to be seen by others. For they make their phylacteries broad and their fringes long, 6 and they love the place of honor at feasts and the best seats in the synagogues 7 and greetings in the marketplaces and being called rabbi by others. 8 But you are not to be called rabbi, for you have one teacher, and you are all brothers. 9 And call no man your father on earth, for you have one Father, who is in heaven. 10 Neither be called instructors, for you have one instructor, the Christ. 11 The greatest among you shall be your servant. 12 Whoever exalts himself will be humbled, and whoever humbles himself will be exalted.

“Phylacteries” were small leather boxes into which the Pharisees placed portions of the Scriptures. They wore these boxes on their foreheads and arms, in literal obedience to Deuteronomy 6:8 and 11:18

They also increased the size of their “tassels” on the hems of their garments

Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you,

“Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs, which outwardly appear beautiful, but within are full of dead people’s bones and all uncleanness. 28 So you also outwardly appear righteous to others, but within you are full of hypocrisy and lawlessness.
