ועבדתם שם אלוהים מעשה ידי אדם, "and there you will serve (worship) a god which is the work of man." This is not a prophecy that the Israelites when in exile in host countries will themselves worship idols, God forbid. The meaning is that once you have been exiled you will become slaves to people worshipping idols, so that indirectly you will be serving such idols (Onkelos).
אשר לא יראון ולא ישמעון ולא יאכלון ולא יריחון, "deities which are neither able to see, to hear, to eat or to smell." In this verse Moses mentions only four of the basic five senses of man, omitting to mention the sense of touch. There was no need to mention that sense separately as it is included in the statement "who cannot eat." There was no need to mention more than one of the two senses that serve as tools of perceptions by the body. The three senses, sight, hearing, and smelling are considered mental, spiritual senses and this is why we often find them associated with God. Examples are: "The Lord saw" (
Genesis 6,
5 and many others) "God heard" (
Numbers 11,
1 and others). "The Lord smelled" (
Genesis 8,
21). When David describes the impotence of the idols in Psalms 115,7, he had to mention that the idols' hands are unable to use the sense of touch, ידיהם ולא ימישון, seeing he had not mentioned the inability of the idols to eat.
From this paragraph we can learn something about the importance of the five senses which are the principal tools man employs in all his activities. They are needed to fulfill the commandments of the Torah, and, inversely, they enable man to commit trespasses against the Torah. Man's reward or punishment is due to the manner in which he employs these five senses. The reason that God provided man with five such senses is that they correspond to the five Books of the Torah. They also correspond to the five occasions on which "light" is mentioned in the story of creation. They also correspond to the five names by which the soul is known. They represent the complement of the body, making it the residence of the soul. The soul displays its activities by means of these five senses This is why the Torah/Bible condemns idolatry by pointing out that these idols cannot use any of their senses. Any image, cast or otherwise, which is devoid of the means of experiencing the sensations we experience by means of our senses is a priori incapable of helping anyone. How can idolaters say to their deities in times of stress: "arise and save us!" These idols are unable to rise, much less save (
compare Jeremiah 2,
27).
The infinite wisdom of the Creator made five different parts of the body the seat of these five senses and made them gateways to the spiritual, abstract soul. Even our "scientists" admit that the manner in which these senses have been "planted" in man is phenomenal and reflects the wisdom of the Creator. The sense of touch extends throughout the body of man, any part of man's exterior feels, tingles, hurts, when coming into contact with other phenomena. The sense of smell extends beyond the boundary of our skin, outwards. We can perceive by means of it matters which are relatively distant. The sense of hearing covers a wider area than the sense of smell, enabling us to perceive things even further distant. The sense of sight enables us to perceive matters far further removed from us than most of the phenomena we can perceive by the sense of hearing. It is the sense which we need most of all.
