Watch out for jealousy, for you may do something horrible, filling the rest of your life with guilt and regret. You can see what jealousy did in the heart of Ishmael after the Babylonians had conquered Jerusalem, and put Gedaliah in as governor in Jerusalem,
“Now it came to pass in the seventh month that Ishmael the son of Nethaniah…of the royal family and of the officers of the king, came with ten men to Gedaliah…at Mizpah…Then Ishmael…and the ten men who were with him, arose and struck Gedaliah…with the sword, and killed him whom the king of Babylon had made governor over the land. Ishmael also struck down all the Jews who were with him…” (Jeremiah 41:1-3).
The king of Babylon would not be too happy when he discovered such a deed, because it was a direct assault on him, since he had made Gedaliah governor. The assassins then left, fearing the wrath of the king, and so they would fear the rest of their lives.
What a way to live!
If you have done something in a jealous rage, repent immediately, and seek the Lord’s forgiveness and guidance so that you do not commit further sin.
