This always made me laugh. You find it in the book of Isaiah.
"A carpenter cuts down cedars; or s/he chooses a holm tree or an oak and lets it grow strong among the trees of the forest; s/he plants a cedar and the rain nourishes it.
"Then it becomes fuel for a human being, s/he takes a part of it and warms himself, s/he kindles a fire and bakes bread; also s/he makes a god and worships it, s/he makes it a graven image and falls down before it.
"Half of it s/he burns in the fire; over the half s/he eats flesh, s/he roasts meat and is satisfied; also s/he warms herself and says, "Aha, I am warm, I have seen the fire!"
"And the rest of it s/he makes into a god, his idol; and falls down to it and worships it; s/he prays to it and says, 'Save me, for you are my God!'
