3. Another sin charged upon them is their trusting in and seeking to foreign aids and succours, and contracting a communion with the Gentile powers (v. 9): Thou wentest to the king, which some understand of the idol they worshipped, particularly Moloch, which signifies a king. "Thou didst every thing to ingratiate thyself with those idols, didst offer incense and sweet ointments at their altars." Or it may be meant of the king of Assyria, whom Ahaz made his court to, or of the king of Babylon, whose ambassadors Hezekiah caressed, or of other kings of the nations whose idolatrous usages they admired and were desirous to learn and imitate, and for that end went and sent to cultivate an acquaintance and correspondence with them, that they might be like them and strengthen themselves by an alliance with them. See here, (1.) What an expense they were at in forming and procuring this grand alliance. They went with ointments and perfumes, either bestowed upon themselves, to beautify their own faces and so make themselves considerable and worthy the friendship of the greatest king, or to be presented to those whose favour they were ambitious of, because a man's gift makes room for him and brings him before great men. "When the first present of rich perfumes was thought too little, thou didst increase them;" and thus many seek the ruler's favour, forgetting that, after all, every man's judgment proceeds from the Lord. So fond were they of those heathen princes that they not only went themselves, in all their airs, to those that were near them, but sent messengers to those that were afar off, ch. xviii. 2. (2.) How much they hereby disparaged themselves and laid the honour of their crown and nation in the dust: Thou didst debase thyself even unto hell. They did so by their idolatries. It is a dishonour to the children of men, who are endued with the powers of reason, to worship that as their god which is the creature of their own fancy and the work of their own hands, to bow down to the stock of a tree. It is much more a dishonour to the children of God, who are blessed with the privilege of divine revelation, to forsake such a God as they know theirs to be for a thing of nought, their own mercies for lying vanities. They likewise debased themselves by truckling to their heathen neighbours, and depending upon them, when they had a God to go to who is all-sufficient and in covenant with them. How did those shame themselves to the highest degree, and sink themselves to the lowest, that forsook the fountain of life for broken cisterns and the rock of ages for broken reeds! Note, Sinners disparage and debase themselves; the service of sin is an ignominious slavery; and those who thus debase themselves to hell will justly have their portion there.
