Isa 40:20
This is the origin of a metal idol. The wooden idol is described in Isa 40:20 : “The man who is impoverished in oblations, he chooseth a block of wood that will not rot; he seeketh for himself a skilful smith, to prepare an idol that will not shake.” He who has fallen into such poverty that he can only offer to his God a poor oblation (terūmâh, accusative, according to Ewald, §284,c), has an idol cut for himself out of a block of wood. That sâkhan (Arab. sakana or sakuna) is an ancient word, is evident from Deu 8:9. The verb yimmōt, like yittōl in Isa 40:15, is a fut. niphal, to be made to shake. A wooden image, which is planed at the bottom, and made heavier below than above, to prevent its falling over with every shock, is to be a god! The thing carries its own satire, even when described with the greatest seriousness.
