"Observe, It is not so much out of compassion to the poor creature that they do it as a concern for their own interest. It is their own ox, and their own ass, that is worth money, and they will dispense with the law of the sabbath for the saving of. Now this was an evidence of their hypocrisy, and that it was not out of any real regard to the sabbath that they found fault with Christ for healing on the sabbath day (that was only the pretence), but really because they were angry at the miraculous good works which Christ wrought, and the proof he thereby gave of his divine mission, and the interest he thereby gained among the people. Many can easily dispense with that, for their own interest, which they cannot dispense with for God's glory and the good of their brethren." - Matthew Henry
