Charles Spurgeon Commentary Jeremiah 10:5

"They are like a palm-tree, of turned work, and speak not: they must needs be borne, because they cannot go. Be not afraid of them; for they cannot do evil, neither is it in them to do good." — Jeremiah 10:5 (ASV)

They are upright as the palm tree, but speak not: they must necessarily be borne, because they cannot go.

Pretty gods they must be! They cannot move, and cannot even stand until they are nailed up, and cannot stir unless they are carried from place to place.

8.

Be not afraid of them; for they cannot do evil, neither also is it in them to do good. Forasmuch as there is none like to you, O LORD; you are great, and your name is great in might. Who would not fear you, O King of nations? for to you it does appertain: forasmuch as among all the wise men of the nations, and in all their kingdoms, there is none like to you. But they are altogether brutish and foolish: the stock is a doctrine of vanities.

To teach people to worship mere stocks and stones, may well be called "a doctrine of vanities."
