Or HaChaim on Exodus 23:33/אור החיים על שמות כ״ג:ל״ג

1 פן יחטיאו אתך לי, "lest they make you sin against Me." The Torah reveals here that imperfection by the Jewish people impacts on the Creator. The logic is as follows: Seeing that the Israelites represent a certain amount of sanctity, they diminish that level of sanctity if they worship idols. Diminishing the amount of sanctity weakens the Israelites' ties with their holy roots, i.e. it impacts on the root of sanctity, i.e. G'd Himself.

2כי יהיה לך למוקש, "for it will become a snare for you." The Torah explains why there is a suspicion that the Israelites could ever agree to trade their honour for such useless forms of religion as these Canaanite deities. G'd explains that it is in the nature of idols to mislead those who worship them into being trapped by them. Our sages in Avodah Zarah 55 explain that there are religions (oracles) which reveal the future to their adherents and which inform them about hidden treasures. G'd was afraid that Jews too would fall victim to such enticements as obtaining knowledge of the future by means of worshiping such oracles.
