Isaiah 40:20

He that is so impoverished that he hath no oblation chooseth a tree that will not rot; he seeketh unto him a cunning workman to prepare a graven image, that shall not be moved.

He that is so impoverished that he hath no oblation,.... Who is so poor that he cannot bring an offering to his God, yet he will have one; and though he cannot purchase a golden or silver one, or one that is gilt, and adorned with either; yet he will have a wooden one, as follows. Some render it, "he that is set over the oblation", which Aben Ezra mentions; that was over the treasury, where the oblations were; the Heathen priest, whose business it was from thence to procure idols to worship. Jerom takes the word Nkom to be the name of a tree that will not rot; and so the Targum renders it,

"he cuts down an ash:''

but the word is descriptive of an idol worshipper; and, according to Gussetius {x}, signifies one that by custom and repeated acts has got skill in such things; and so Jarchi: hence

he chooseth a tree that will not rot: he goes to the forest, and chooses the best tree for his purpose he can find, even one that will not rot, as the cypress; and though he cannot get an idol made of metal, but is forced to have one of wood, yet he will get the best he can, that will last longest, an incorruptible deity, as he fancies:

he seeketh unto him a cunning workman, to prepare a graven image that shall not be moved: having decided upon his tree, and what sort of wood to make his god of, he looks out for an ingenious carpenter and carver, a good workman, to make it in the form of an image, and grave, or rather carve it, in the best manner he can, and then fasten it in a proper place, that it may not fall; a poor helpless deity, that cannot secure itself, and much less be of any service to its worshippers.
