'Food Sacrificed To Idols' in the Bible

For if someone with a weak conscience sees you, who have [correct] knowledge [in this matter], eating in an idol's temple, will he not be encouraged to eat food sacrificed to idols?

"But I have a few things against you because you have people there [in the church] who hold to the teaching of Balaam, who taught Balak to place a stumblingblock in front of the Israelites, [causing them] to eat food sacrificed to idols and to be sexually immoral [See Num. 23-24].
