John Gill Commentary Ezekiel 20:16

"because they rejected mine ordinances, and walked not in my statutes, and profaned my sabbaths: for their heart went after their idols." — Ezekiel 20:16 (ASV)

Because they despised my judgments, and walked not in my
statutes, but polluted my sabbaths
Which were just causes of divine resentment and anger; (See Gill on Ezekiel 20:13); for their heart went after their idols ;
which they had served in Egypt; and that led them off from the true worship and service of God; no man can serve two masters; if he holds to the one, and his heart is towards him, he will despise the other; and yet these idols were no other, as the word signifies, than dunghill gods, as in (Ezekiel 20:16) ; and such are all worldly things, in comparison of God, that the heart of man is going after.
