1 Corinthians 10:22 - Matthew Poole's English Annotations on the Holy Bible

Jealousy is a violent passion in a man, not bearing a companion or a rival as to a thing or person which he loveth. It is in holy writ applied unto God, not to signify any such extravagancy, excess, or vehemence, as attendeth that passion in men, but only his just displeasure at the giving that homage to any creature which is due to him alone. It is most applied to God to express his anger against those who give Divine homage to idols; the worship of God being a great piece of his glory which he hath said he will not give to another, nor his praise to graven images, Isaiah 42:8. Hence divines observe, that jealousy is attributed to God in the second commandment, which concerns the more external worship of God, to deter men from the violation of it, Exodus 20:5. So Exodus 34:14 Deuteronomy 4:24, Deuteronomy 5:9 6:16, and in many other texts, it signifieth, that the worship of God is a thing that he is very tender of, and that his will is to endure no creature to share with him in it; and that his wrath shall flame against that man that offers to make any creature such a sharer. So that it is not safe for any to do any thing of that nature, unless he could fancy himself to be stronger than God; for he that doth it, must expect the power and strength of God to be engaged against him. Thus the apostle had dissuaded them from eating meat sacrificed to idols in the idol's temple, from the impiety of it, it being a species of idolatry, against which God hath signally revealed his wrath. He returns in the following verses to an argument, by which he had before dissuaded it, 1 Corinthians 8:1-13, as it was against charity, and the duty of love, in which they were indebted to their brethren.
