Matthew Henry Commentary Hosea 8:11-14

"Because Ephraim hath multiplied altars for sinning, altars have been unto him for sinning. I wrote for him the ten thousand things of my law; but they are counted as a strange thing. As for the sacrifices of mine offerings, they sacrifice flesh and eat it; but Jehovah accepteth them not: now will he remember their iniquity, and visit their sins; they shall return to Egypt. For Israel hath forgotten his Maker, and builded palaces; and Judah hath multiplied fortified cities: but I will send a fire upon his cities, and it shall devour the castles thereof." — Hosea 8:11-14 (ASV)

It is a great sin to corrupt the worship of God, and it will be charged as sin against all who do so, however plausible their excuses may seem.

The Lord had caused His law to be written for them, but they did not care to know it and would not obey it.

Man, by the temples he builds, seems to be mindful of His Maker, yet he has truly forgotten Him, because he has cast off all fear of Him. Indeed, no one has ever hardened his heart against God and prospered.

As long as people despise the truths and precepts of God's Word and the ordinances of His worship, all the observances and offerings of their own devising, however costly, will be counted as sin to them. For only those services are acceptable to God that are performed according to His Word and through Jesus Christ.
