Note 6 at 1Co 10:22: Paul had used all these other arguments to try to make these Corinthians see the light (see note 1 at 1Co 10:1). Here, he got tough. He reminded them that God is a jealous God, and He was taking a dim view of their actions.

The Lord proclaimed Himself to be a jealous God (Ex 20:5, 34:14; and De 5:9). Others, writing under the inspiration of the Holy Ghost, proclaimed the Lord as a jealous God (De 4:24, 6:15; Jos 24:19; Ps 78:58; and Na 1:2). There are also recorded instances of His jealousy (De 32:16 and 21).

Jas 4:4 says, "Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God." In the very next verse (Jas 4:5), James referred to these scriptures speaking of God as a jealous God. God takes our flirting with someone else very seriously.

Paul used all possible motivations to get these people to stop knowingly eating meat offered to idols.
