This warning to the nations is very easy to understand. God is a jealous God. He is jealous for His reputation as the only God. And He is jealous for His land and people Israel.
“Therefore wait for Me,” says the Lord, “Until the day I rise up for plunder; My determination is to gather the nations to My assembly of kingdoms, to pour on them My indignation, all My fierce anger; all the earth shall be devoured with the fire of My jealousy.
PRAY FOR YOUR NATION TO REPENT FOR THE WORSHIP OF FALSE GODS AND ITS TREATMENT OF ISRAEL.
