Jesaja 44:20

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 certain, that he does not think of saving his soul, and it never occurs to him to say, "Is there not a lie in my right hand?" All that belongs to idolatry is sheqer - a fabrication and a lie. רעה means primarily to pasture or tend, hence to be concerned about, to strive after. הותל is an attributive, from tâlal - hâtal, ludere, ludificare (see at Isa 30:10).

God, by the prophet, goes on in this chapter, as before, I. To encourage his people with the assurance of great blessings he had in store for them at their return out of captivity, and those typical of much greater which the gospel church, his spiritual Israel, should partake of in the days of the Messiah; and hereby he proves himself to be God alone against all pretenders (Isa 44:1-8). II. To expose the sottishness and amazing folly of idol-makers and idol-worshippers (Isa 44:9-20). III. To ratify and confirm the assurances he had given to his people of those great blessings, and to raise their joyful and believing expectations of them (Isa 44:21-28).
