V.1-12 Moses married a Gentile wife, named Zipporah. She is sent away, but now returns. A picture of us believers. We are the Gentile bride of Christ. During the time Israel goes through the tribulation (see your chart) we believers, the church, are away in heaven. But during the millennium, the church and Israel are going to rejoice together that Christ is the Center of all. It will be a day of unspeakable joy to Him, and every part of His joy will awaken a response in the heart of the “Lamb’s wife,” the believers (Rev. 19:6-9).
V.13-27 This section is a picture of the Lord’s reign during the millennium. In Psalm 72:2-3 there is a nice statement about this great time. Everything will be perfectly in order. However, we must not overlook the fact that Moses himself made a mistake in listening to Jethro. It sounded like such good advice, but if God had given Moses the job to do, then God would give him the strength for it.
