Jeremiah 10:3

The customs of the people are vain, i.e. such courses, institutions, idolatrous customs, and ceremonies as these, that many people follow, they are vain, and it is a foolish and wicked thing that any that profess the true God should give heed to such lying vanities. One cutteth a tree out of the forest: here he annexeth their idolatry to their astrology: q.d. They cut down timber to make the images and representations of these stars and planets that they fear and worship as gods, either in memorial of them, when they could not see them, or else upon a superstitious conceit that the stars which they worshipped did by some magic art convey some virtue or spirit into these statues or images; or rather, he doth set forth the folly of the heathen, that whereas for the matter of them, they are but a piece of wood, a tree out of the forest; and as to the form of them, no other than the carver, a sorry man, is pleased to put them into by his axe, which I suppose is here put for any cutting tool of the artist whereby he shapes it; yet they are afraid of these, as if they were gods, Isaiah 40:20. See Poole on "Jeremiah 8:2".
