إشعياء ٤٠:٢٠

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) (Note: Both forms occur in this sense, according to the evidence of original sources, with the common imperative yaskunu, the infinitive sukūne passed over by Freytag, the verbal substantive maskane, and the adjective miskin or meskin, primarily to be forced to inactivity through weakness, destitution, or outward influences, not to be able to move and exert one's self; or, more particularly, not to be able to defend one's self (as it were to be obliged to sit still or keep still). Hence more especially opibus et facultatibus carens, being in distress, destitute, poor.) 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.

40:20 image that won’t fall down: This is a sarcastic remark; it would be embarrassing if the idol did not even have the power to remain standing (see 40:18; 41:7; 1 Sam 5:4).
