It is a proverbial expression used amongst them, against such as would pretend a great niceness and scrupulosity about, and zeal for, little things, but in matters of much higher concern and moment were not nice and scrupulous at all: and this indeed is both a certain note and an ordinary practice of hypocrites. There is no man that is sincere in his obedience to God, but hath respect to all God’s commandments, Psa_119:6. Though some duties be greater, of more moment for the honour and glory of God, than others, which a good man will lay the greatest stress upon, yet he will neglect nothing which the law of God enjoins him. But concerning hypocrites, these two things are always true:
1. They are partial in their pretended obedience.
2. They always lay the greatest stress upon the least things of the law, bodily labour and exercise, and those things which require least of the heart, and least self-denial.
