Verse 16. - Their heart went after their idols. The words may point generally to the fact that the idolatrous tendencies of the people, though suppressed, were not really eradicated. The history of Baal-peor (Numbers 25:3-9) shows how ready they were to pass into act, and Amos 5:25, 26 implies a tradition of other like acts during the whole period of the wanderings in the wilderness.

20:10-26. The history of Israel in the wilderness is referred to in the new Testament as well as in the Old, for warning. God did great things for them. He gave them the law, and revived the ancient keeping of the sabbath day. Sabbaths are privileges; they are signs of our being his people. If we do the duty of the day, we shall find, to our comfort, it is the Lord that makes us holy, that is, truly happy, here; and prepares us to be happy, that is, perfectly holy, hereafter. The Israelites rebelled, and were left to the judgments they brought upon themselves. God sometimes makes sin to be its own punishment, yet he is not the Author of sin: there needs no more to make men miserable, than to give them up to their own evil desires and passions.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.
