Jerome : (Verse 18 and following) To whom then will you liken God, or what image will you set before Him? Can the craftsman make a graven image, or the goldsmith overlay it with gold, and the silversmith spread silver plates upon it? Or perhaps the skilled craftsman chooses a piece of wood that will not rot and seeks out a proficient artisan to fashion an image that will not move. Having described the greatness of God and shown His power in part, and having compared the nations and islands to a drop from a bucket and a speck of dust on the scales, and having refuted the use of ashes and sacrificial ceremonies, he teaches those who follow that all the nations before Him are as nothing and are counted by Him as less than nothing. To whom then will you liken God, or what image will you set before Him, who is a Spirit, who is in all things and is everywhere present, and who holds the earth in His hand as if it were a small container? At the same time, he derides the foolishness of nations, because the artisan, whether a blacksmith or a goldsmith or a silversmith, makes their own god and fastens it with nails and firmly establishes it so that it is not blown away by the gusts of wind. And this is what he introduces: a wise artisan has chosen a strong and incorruptible wood, which is called Amsuchan in Hebrew; this type of wood is incorruptible and is used especially for making idols. However, he says this so that, rejecting idols, the way of the Gospel may be followed, and all wrongs may be made right; the valleys may be lifted up, and the hills may be brought low; and the glory of the Lord may be revealed, so that all flesh may see the salvation of God. According to the tropology, we can say that the leaders of the heretics are rebuked for inventing diverse idols from their own hearts; either by the charm of eloquence, which is interpreted as silver; or by the brilliance of gold, which appeals to the senses; or by the incorruptibility of wood, which represents the baser doctrines: and they are considered permanent by the inventors, and are supported by dialectical skill, so that they may not be moved or fall, but may stand firm on a solid root. — Commentary on Isaiah
