As if it had been a light thing for him to walk in the sins of Jeroboam - Idolatries are not exclusive. Ahab, while he detested the pure worship of Yahweh, and allowed Jezebel to put to death every "prophet of the Lord" whom she could find 1 Kings 18:4, readily tolerated the continued worship of the "calves," which had no doubt tended more and more to lose its symbolic character, and to become a thoroughly idolatrous image-worship.

Eth-baal - Identified with the Ithobalus of Menander, who reigned in Tyre, probably over all Phoenicia, within 50 years of the death of Hiram. This Ithobalus, whose name means "With him is Baal," was originally priest of the great temple of Astarte, in Tyre. At the age of 36 he conspired against the Tyrian king, Pheles (a usurping fratricide), killed him, and seized the throne. His reign lasted 32 years, and he established a dynasty which continued on the throne at least 62 years longer. The family-tree of the house may be thus exhibited:

Lineage of Eth-Baal Eth-baal Badezor Jezebel Matgen (Belus of Virgil) Pygmalion Dido (founder of Carthage)

Hence, Jezebel was great-aunt to Pygmalion and his sister Dido.

Served Baal - The worship of Baal by the Phoenicians is illustrated by such names as IthoBAL, HanniBAL, etc. Abundant traces of it are found in the Phoenician monuments.

He took to wife Jezebel - This was the head and chief of his offending; he took to wife, not only a heathen, but one whose hostility to the true religion was well known, and carried to the utmost extent.

1. She was the idolatrous daughter of an idolatrous king;

2. She practiced it openly;

3. She not only countenanced it in others, but protected it, and gave its partisans honors and rewards;

4. She used every means to persecute the true religion;

5. She was hideously cruel, and put to death the prophets and priests of God;

6. And all this she did with the most zealous perseverance and relentless cruelty.

Notwithstanding Ahab had built a temple, and made an altar for Baal, and set up the worship of Asherah, the Sidonian Venus, which we, 1 Kings 16:33, have transformed into a grove; yet so well known was the hostility of Jezebel to all good, that his marrying her was esteemed the highest pitch of vice, and an act the most provoking to God, and destructive to the prosperity of the kingdom.

And it came to pass, as if it had been a light thing for him to walk in the sin of Jeroboam the son of Nebat,.... To worship the golden calves he set up:

that he took to wife Jezebel the daughter of Ethbaal king of the Zidonians; who is called Ithobalus and Itobalus king of the Tyrians, by Heathen historians (h); and, by Theophilus of Antioch (i), Juthobalus, priest of Astarte; for Tyre and Zidon were under one king. This woman was not only of another nation, and an idolater, but a very filthy woman, and is made the emblem of the whore of Rome, Revelation 2:20.

and went and served Baal, and worshipped him that is, went to Zidon and Tyre, and worshipped his wife's gods, which were either Jupiter Thalassius, the god of the Zidoaians, or Hercules, whom the Tyrians worshipped.

And it came to pass, as if it had been a light thing for him to walk in the sins of Jeroboam the son of Nebat, that he took {m} to wife Jezebel the daughter of Ethbaal king of the Zidonians, and went and served Baal, and worshipped him.

(m) By whose influence he fell into wicked and strange idolatry and cruel persecution.

16:31 A light thing - The Hebrew runs, was it a light thing, and c, that is, was this but a small sin, that therefore he needed to add more abominations? Where the question, as is usual among the Hebrews, implies a strong denial; and intimates, that this was no small sin, but a great crime; and might have satisfied his wicked mind, without any additions. Jezebel - A woman infamous for her idolatry, and cruelty, and sorcery, and filthiness. Eth - baal - Called Ithbalus, or Itobalus in heathen writers. So she was of an heathenish and idolatrous race. Such as the kings and people of Israel were expressly forbidden to marry. Baal - The idol which the Sidonians worshipped, which is thought to be Hercules. And this idolatry was much worse than that of the calves; because in the calves they worshipped the true God; but in these, false gods or devils.

as if...: Heb. was it a light thing, etc

16:29-34 Ahab did evil above all that reigned before him, and did it with a particular enmity both against Jehovah and Israel. He was not satisfied with breaking the second commandment by image-worship, he broke the first by worshipping other gods: making light of lesser sins makes way for greater. Marriages with daring offenders also imbolden in wickedness, and hurry men on to the greatest excesses. One of Ahab's subjects, following the example of his presumption, ventured to build Jericho. Like Achan, he meddled with the accursed thing; turned that to his own use, which was devoted to God's honour: he began to build, in defiance of the curse well devoted to God's honour: he began to build, in defiance of the curse well known in Israel; but none ever hardened his heart against God, and prospered. Let the reading of this chapter cause us to mark the dreadful end of all the workers of iniquity. And what does the history of all ungodly men furnish, what ever rank or situation they move in, but sad examples of the same?
