Isaiah 44:20

“He feedeth of ashes, &c.] That is, the idolater delights in his idol, pleases himself with seeks comfort and satisfaction from it, fills and feeds himself with hopes and expectations of being helped and delivered by it; but this is all vain hope, a mere delusion; it is as if a man fed on ashes instead of food; it is feeding on that which has no savour nor substance, can yield no nourishment, but, on the contrary, is pernicious and hurtful; and it is like Ephraim’s feeding on wind, (<281201>Hosea 12:1) or on chaff instead of wheat, (<242328>Jeremiah 23:28) and so such who feed upon and delight themselves in sinful lusts, or false doctrines, may be said to feed on the same sort of food: and…”

“feedeth on ashes--figuratively, for the idolater delights in what is vain (Pro 15:14; Hos 12:1). "Feedeth on wind." There is an allusion, perhaps, also, to the god being made of a tree, the half of which was reduced to ashes by fire (Isa 44:15-17); the idol, it is implied, was no better, and could, and ought, to have been reduced to ashes like the other half. deceived heart--The heart and will first go astray, then the intellect and life (Rom 1:28; Eph 4:18). lie in . . . right hand--Is not my handiwork (the idol) a self-deceit?”

“He feedeth on ashes - There have been various interpretations of this. Jerome renders it, ‘A part of it is ashes;’ the Chaldee, ‘Lo! half of the god is reduced to ashes;’ the Septuagint, ‘Know thou that their heart is ashes.’ The word rendered here ‘feedeth’ (רעה ro‛eh) means properly “to feed, graze, pasture”; and then, figuratively, to delight, or take pleasure in any person or thing Proverbs 13:20; Proverbs 15:14; Proverbs 28:7; Proverbs 29:3. In Hosea 12:1, ‘Ephraim feedeth on wind,’ it means to strive after something vain or unprofitable; to seek that which will prove to be vain and unsatisfactory. So here it means, that in their idol-service they would not obtain that which they…”

“Ashes - An unprofitable and pernicious food, and no less unsatisfying and mischievous is the worship of idols. Deceived heart - A mind corrupted and deceived by deep prejudice, gross error, and especially by his own lusts. Turned - From the way of truth. Deliver - From the snares and dangers of idolatry. Is there not - What is this idol which I set at my right - hand, as the true God is said in scripture to be at the right - hand of his people; which I highly honour, for the most honourable place was on the right - hand; to which I look for relief and assistance, which God in scripture is said to afford to his people, by being at and holding their right - hand. What, I say, is this idol? Is…”

“feedeth: Job 15:2; Psa 102:9; Pro 15:14; Hos 12:1; Luk 15:16 a deceived: Kg1 22:20-23; Job 15:31; Hos 4:12; Rom 1:20-22, Rom 1:28; Th2 2:11; Ti2 2:13; Rev 12:9, Rev 13:14, Rev 18:23, Rev 20:3 Is there: Isa 28:15-17; Jer 16:19; Hab 2:18; Th2 2:9-11; Ti1 4:2 Isaiah 44:21”

“This exposure of the infatuation of idolatry closes with an epiphonem in the form of a gnome (cf., Isa 26:7, Isa 26:10). "He who striveth after ashes, a befooled heart has led him astray, and he does not deliver his soul, and does not think, Is there not a lie in my right hand?" We have here a complete and self-contained sentence, which must not be broken up in the manner proposed by Knobel, "He hunts after ashes; his heart is deceived," etc. He who makes ashes, i.e., things easily scattered, perishable, and worthless, the object of his effort and striving (compare rūăch in Hos 12:2), has bee led astray from the path of truth and salvation by a heart overpowered by delusion; he is so…”
