Charles Spurgeon Commentary Isaiah 44:15

"Then shall it be for a man to burn; and he taketh thereof, and warmeth himself; yea, he kindleth it, and baketh bread: yea, he maketh a god, and worshippeth it; he maketh it a graven image, and falleth down thereto." — Isaiah 44:15 (ASV)

Then shall it be for a man to burn: for he will take thereof, and warm himself;

He cuts up part of the tree for fuel, and warms himself with it.
