The carpenter, etc. When the smith has done his part in the formation of tools, the carpenter is called into action. His proceedings are traced "extragressively." (Delitzsch). First, he is regarded as in possession of his block of wood.
On this he proceeds to stretch out his rule, to obtain the idol's length and breadth. Then he marks out on the block a rough outline with red chalk (sered). After this he pares away the superfluous wood with planes, or chisels, and marks out the limbs more accurately with the compass, planing and measuring until he has brought the rough block into the figure of a man, and impressed on it something of the beauty of a man, so that it may seem worthy of remaining in the place where it is set up, whether temple or private house.
But there is something necessarily anterior to all this. To obtain his block, the carpenter must first cut down a tree, or have one cut down for him (Isaiah 44:14); to obtain a tree, he (or some one for him) must have planted it; for the tree to have grown to a fitting size, the rain must have watered it.
So the very existence of these wooden idols depends ultimately on whether it has rained or not—i.e; whether God has given his rain or withheld it.
