Matthew 23:4

For they bind heavy burdens Not only insisting upon the most minute circumstances of the ceremonial law, called a yoke, Acts 15:10; and pressing the observation of them with more strictness and severity than God himself did; but by adding to his word, and imposing their own inventions and traditions under the highest penalties: witness their many additions to the law of the sabbath, by which they made that day a burden, which was designed to be a joy and delight: but they themselves will not move them with one of their fingers They press upon the people a strictness in religion which they themselves will not be bound by, but secretly transgress their own traditions, which they publicly enforce.
