15 Take therefore good heed to yourselves; for you saw no kind of form on the day that Yahweh spoke to you in Horeb out of the midst of the fire.

Ye saw no manner of similitude - Howsoever God chose to appear or manifest himself, he took care never to assume any describable form. He would have no image worship, because he is a Spirit, and they who worship him must worship him in Spirit and in truth. These outward things tend to draw the mind out of itself, and diffuse it on sensible, if not sensual, objects; and thus spiritual worship is prevented, and the Holy Ghost grieved. Persons acting in this way can never know much of the religion of the heart.
Take ye therefore good heed unto yourselves; for ye saw no (l) manner of similitude on the day [that] the LORD spake unto you in Horeb out of the midst of the fire:
(l) Signifying, that destruction is prepared for all who make any image to represent God.
Take ye therefore good heed unto yourselves,.... As to keep all the laws given them, so particularly to avoid idolatry:
for ye saw no manner of similitude on the day the Lord spake unto you in Horeb out of the midst of the fire; and therefore, as they had nothing that directed and led them, so they had nothing that could be a temptation to them, to make any form or likeness, and worship it.
A PARTICULAR DISSUASIVE AGAINST IDOLATRY. (Deuteronomy. 4:14-40)
Take . . . good heed . . . for ye saw no manner of similitude--The extreme proneness of the Israelites to idolatry, from their position in the midst of surrounding nations already abandoned to its seductions, accounts for their attention being repeatedly drawn to the fact that God did not appear on Sinai in any visible form; and an earnest caution, founded on that remarkable circumstance, is given to beware, not only of making representations of false gods, but also any fancied representation of the true God.
As the Israelites had seen no shape of God at Horeb, they were to beware for their souls' sake (for their lives) of acting corruptly, and making to themselves any kind of image of Jehovah their God, namely, as the context shows, to worship God in it. (On pesel, see at Exodus 20:4.) The words which follow, viz., "a form of any kind of sculpture," and "a representation of male or female" (for tabnith, see at Exodus 25:9), are in apposition to "graven image," and serve to explain and emphasize the prohibition.
In Horeb - God, who in other places and times did appear in a similitude in the fashion of a man, now in this most solemn appearance, when he comes to give eternal laws for the direction of the Israelites in the worship of God, and in their duty to men, purposely avoids all such representations, to shew that he abhors all worship of images, or of himself by images of what kind soever, because he is the invisible God, and cannot be represented by any visible image.
