Ye shall make you no idols nor graven image, neither rear you up a standing image, neither shall ye set up any image of stone in your land, to bow down unto it. The word idols (elilim) means the "nothings" which the heathen substituted for the Lord God.
The graven image (here meaning a carved wooden image), the standing image (meaning a sacred pillar), and the image of stone (that is, a sculptured stone idol), are the three forms of images under which adoration was paid, whether to the true God or to a false doily.
The expression, to bow down unto (or towards) it, forbids worshipping before an image as well as worshipping an image.
