(2.) To be very cautious: "Take heed of missing it, either on the right hand or on the left, for there are errors and extremes on both hands. Take heed of running either into a profane neglect of any of God's institutions or into a superstitious addition of any of your own inventions." They must especially take heed of all approaches towards idolatry, the sin to which they were first inclined and would be most tempted, v. 7. [1.] They must not acquaint themselves with idolaters, nor come among them to visit them or be present at any of their feasts or entertainments, for they could not contract any intimacy nor keep up any conversation with them, without danger of infection. [2.] They must not show the least respect to any idol, nor make mention of the name of their gods, but endeavour to bury the remembrance of them in perpetual oblivion, that the worship of them may never be revived. "Let the very name of them be forgotten. Look upon idols as filthy detestable things, not to be named without the utmost loathing and detestation." The Jews would not suffer their children to name swine's flesh, because it was forbidden, lest the name of it should occasion their desiring it; but, if they had occasion to speak of it, they must call it that strange thing. It is a pity that among Christians the names of the heathen gods are so commonly used, and made so familiar as they are, especially in plays and poems: let those names which have been set up in rivalship with God be for ever loathed and lost. [3.] They must not countenance others in showing respect to them. They must not only not swear by them themselves, but they must not cause others to swear by them, which supposes that they must not make any covenants with idolaters, because they, in the confirming of their covenants, would swear by their idols; never let Israelites admit such an oath. [4.] They must take heed of these occasions of idolatry, lest by degrees they should arrive at the highest step of it, which was serving false gods, and bowing down to them, against the letter of the second commandment.
