Isaiah 57:9

“And thou wentest to the king with ointment, &c.] To the kings of the earth, the singular for the plural, with whom the whore of Rome has committed fornication or idolatry, in allusion to harlots, who, in order to render themselves the more agreeable to their lovers, anointed themselves with ointment: this may respect the grace of the Spirit of God, which the church of Rome pretends to give by administration of the sacraments, which it is said confer grace “ex opere operato”; and the extreme unction given as a meetness for heaven, in the last moments of life: and didst increase thy perfumes; after the manner of harlots, who, to ingratiate themselves with men, use much perfumes: this may…”

“the king--the idol which they came to worship, perfumed with oil, like harlots (Jer 4:30; Eze 23:16, Eze 23:40). So "king" means idol (Amo 5:26; Zep 1:5); (malcham meaning "king") [ROSENMULLER]. Rather, the king of Assyria or Egypt, and other foreign princes, on whom Israel relied, instead of on God; the "ointment" will thus refer to the presents (Hos 12:1), and perhaps the compliances with foreigners idolatries, whereby Israel sought to gain their favor [LOWTH] (Isa 30:6; Eze 16:33; Eze 23:16; Hos 7:11). send . . . messengers far off--not merely to neighboring nations, but to those "far off," in search of new idols, or else alliances. even unto hell--the lowest possible degradation.”

“And thou wentest to the king - Margin, ‘Respectedst.’ Jerome renders this, ‘Thou hast adorned thyself with royal ointment, and hast multiplied thy painting; and evidently understands it as a continuance of the sentiment in the previous verses as referring to the kind of decoration which harlots used. The Septuagint renders it, ‘Thou hast multiplied thy fornication with them, and hast done it with many who are far from thee.’ The Chaldee renders it, ‘When thou didst keep the law thou wert prosperous in the kingdom; and when thou didst abound in good works, then thine armies were multiplied.’ Lowth supposes that the king of Egypt or Assyria is intended, and that the prophet refers to the fact,…”

“The King - The king of Assyria, called the king by way of eminency, to whom the Israelites in the days of Isaiah were very prone to trust, and send presents. And so the prophet passes from their idolatry to another sin, even their confidence in Heathen princes. Increase - Didst send great quantities. Far off - Into Assyria, which was far from Judea. Debase - Thou wast willing to submit to the basest terms to procure their aid. Isaiah 57:10”

“thou wentest to the king: or, thou respectedst the king, Isa 30:1-6, Isa 31:1-3; Kg2 16:7-11; Eze 16:33, Eze 23:16; Hos 7:11, Hos 12:1 perfumes: Pro 7:17 and didst debase: Isa 2:9; Col 2:18 Isaiah 57:10”

“In the closest reciprocal connection with this God-forgetting, adulterous craving for the favour of heathen gods, stood their coquetting with the heathen power of the world. "And thou wentest to the king with oil, and didst measure copiously thy spices, and didst send thy messengers to a great distance, and didst deeply abase thyself, even to Hades. Thou didst become weary of the greatness of thy way; yet thou saidst not, It is unattainable: thou obtainedst the revival of thy strength: therefore thou wast not pained." The first thing to be noticed here, is one that has been overlooked by nearly all the modern commentators, viz., that we have here a historical retrospect before us. And…”
