Isaiah 16:3-5. “Take counsel, execute judgment; make thy shadow as the night in the midst of the noonday; hide the outcasts; bewray not him that wandereth. Let Mine outcasts dwell with thee, Moab; be thou a covert to them from the face of the spoiler: for the extortioner is at an end, the spoiler ceaseth, the oppressors are consumed out of the land. And in mercy shall the throne be established: and He shall sit upon it in truth in the tabernacle of David, judging, and seeking judgment, and hasting righteousness.”
These verses refer to the time of the future great tribulation,
the time of Jacob’s trouble.” At the end of the warfare of Har-Magedon, the King of the North will pass through Palestine, “the glorious land,” on his way to conquer Egypt. But Edom, Moab, and Ammon will “be delivered” (Dan. 11:41).Satan will have instigated Antichrist to lead the armies of the Roman power to exterminate the Jewish people, and particularly the godly remnant who have already turned to Jesus, Messiah. Those Jews will have escaped to the rocky, deep valleys and the mountains in Moab (Matt. 24:16). Moab is to guard them and nourish them there for 3 1/2 years (Rev. 12:14, with verse 6).
Moab is to listen to godly counsel, and make godly judgments. They are to be the refuge for believing Jews, hiding them. To bewray is to make accusations, to speak unkindly about someone, to betray people.
The believing Jews who survive in Petra of Moab will be the nucleus God uses to establish His kingdom in Jerusalem. The spoiler and the extortioner is Antichrist, who promised much but meant not a word he said.
