Joshua 23:7

“That ye come not among these nations, those that remain among you, etc.] That remained unsubdued, or that were suffered to dwell among them, being tributaries to them; with these they were not to converse freely and familiarly, nor to carry on trade and commerce with them, nor enter into any alliances or marriages with them, and not even attend any of their feasts, and especially their idolatrous ones: neither make mention of the name of their gods; not in common conversation, and still less in any religious matters; never with any reverence of them, or in any respectable manner; but always with indignation and contempt, calling them dunghill gods, and the like, as they often are in…”

“Come not - That is, avoid all familiar converse and contracts, but especially marriages with them. Name their gods - To wit, unnecessarily and familiarly, lest the mention of them breed discourse about them, and so by degrees bring to the approbation and worship of them. Nor cause - Nor require nor compel the Gentiles to swear by them, as they used to do; especially in leagues and contracts. It is pity, that among Christians, the name of the Heathen God's are so commonly used, especially in poems. Let those names which have been set up in rivalship with God, be forever loathed and lost. Nor bow - Neither give them any inward reverence, or outward adoration. Here is an observable gradation,…”

“23:7 Do not even mention . . . swear by . . . serve . . . or worship them: These four actions describe progressive involvement with idolatry.”

“That ye come: Have no civil or social contacts with them, as these will infallibly lead to spiritual affinities, in consequence of which, ye will make honourable "mention of the name of their gods," "swear by them" "and serve" them in their abominable rites; and "bow yourselves unto them," as your creators and preservers. All this will follow by simply coming among them. He who walks in the counsel of the ungodly, will soon stand in the way of sinners, and sit in the seat of scorners.
