'Things Offered to Idols' in the Bible

But concerning the gentile believers, we have written to them and decided that they should observe no such thing, save only to abstain from things offered to idols, and from blood, and from what hath been strangled, and from fornication.

For if any one see thee, who hast knowledge, at table in an idols temple, will not the conscience of him that is weak be emboldened to eat the things offered to idols?
