Ezekiel 20:28

28. They offered there their sacrifices They were enticed into the evil Canaanitish worship against which they were ever being warned (Hosea 8:11; Hosea 8:13; Hosea 9:1; Amos 4:4; Amos 5:21; Jeremiah 2:20; Jeremiah 3:6). It is now seen from the Baal sacrifice tablets (600-500 B.C.) recently discovered, that in many details the form of the ritual closely resembled that of the Hebrews. (See MacDonald’s Massera-Carthago, 1897.) This made it easier for unspiritual and sensually inclined Israelites to forget the essential differences between these sacrificial cults. (See also notes Ezekiel 6:13; Ezekiel 8:14-15.)

The provocation of their offering Disobedient or heathenish offerings were an insult to the one true God.
