John Gill Commentary Leviticus 26:15

"and if ye shall reject my statutes, and if your soul abhor mine ordinances, so that ye will not do all my commandments, but break my covenant;" — Leviticus 26:15 (ASV)

And if you shall despise my statutes Which is an aggravated sin; to be negligent hearers of the commands of God is bad, not to be doers of them worse, but to treat them with contempt is worse still:

or if your soul abhor my judgments: which is worst of all, to despise them as if not wisely or righteously made is a dreadful reflection upon the Maker of them; but to abhor them as bad things, not fit to be regarded, but to be had in the utmost detestation, is shocking impiety:

so that you will not do all my commandments; nor any of them, but are set against them, and determined and resolved on the contrary:

[but] that you break my covenant; the covenant made with them at Sinai, when they promised, on their part, that they would hearken and be obedient, (Exodus 24:7) .
