“And the people of Gad and the people of Reuben answered, ‘What the Lord has said to your servants, we will do. We will pass over armed before the Lord into the land of Canaan, and the possession of our inheritance shall remain with us beyond the Jordan'” (Numbers 32:31-32, ESV).
In Numbers 32 the Israelites are preparing for the conquest of the promised land. The people of the tribes of Reuben and Gad requested that Moses allow them to settle in lands on the east side of the Jordan River, which was not within the boundaries of the promised land. They wanted to settle east of the Jordan because they owned large herds of livestock and there was good grazing land there.
At first Moses resisted their request pointing out that they were disobeying God just like their fathers who died during their forty-year wandering in the wilderness because they rebelled against the plan to possess the land God had promised.
So, the tribes of Reuben and Gad struck a deal with Moses that they would settle their families and livestock on the east side of the Jordan but their fighting men would take up arms and lead in the battles against the inhabitants of the land until all the people groups in the land of Canaan were subdued. If they stayed until the war in Canaan was over, then the lands on the east side of the Jordan would be their inheritance.
“Then the Lord said to Moses, ‘When you take a census of the Israelites to count them, each one must pay the Lord a ransom for his life at the time he is counted. Then no plague will come on them when you number them. Each one who crosses over to those already counted is to give a half shekel… This half shekel is an offering to the Lord. All who cross over, those twenty years old or more, are to give an offering to the Lord'” (Exodus 30:13-14, NIV).
The census was actually a way to determine a record of military manpower. But, when Moses enlisted men for military service, he was also to take a ransom from each twenty-year-old or more male and use it for the construction and ministry of the Tabernacle.
“Crossing over to those already counted” literally meant passing over to those who are mustered. It meant joining the ranks of the enlisted men. By passing muster the Israelite male effectively became a soldier in the Israeli militia–the Lord’s army.
“I will put contempt between you and the woman, between your offspring and hers. They will strike your head, but you will strike at their heels.”” (Genesis 3:15, CEB).
Evil in the Old Testament is not personified as it is in the New Testament. Depending on your interpretation of the Hebrew word for Satan, meaning adversary, the term is more often a designation than a proper name in the Old Testament.
The Apostle Paul associates the serpent in Genesis 3 with a personified devil: “But I’m afraid that your minds might be seduced in the same way as the snake deceived Eve with his devious tricks. You might be unable to focus completely on a genuine and innocent commitment to Christ” (2 Corinthians 11:3, CEB).
The Apostle John clearly delineates the Tempter in the Garden of Eden as Satan or the devil: “So the great dragon was thrown down. The old snake, who is called the devil and Satan, the deceiver of the whole world, was thrown down to the earth; and his angels were thrown down with him” (Revelation 12:9, CEB). The word “old” here refers to the fact that Satan’s appearance on Earth was at an early stage of the world’s history and has long been occupied with the task of deceiving and opposing God’s elect.
“Be strong and courageous! Do not tremble or be dismayed, for the Lord your God is with you wherever you go!” (Joshua 1:9, NASB).
After Moses died, God commissioned Joshua to take leadership and military command over Israel and lead Israel into the promised land. But there were many evil and unfriendly people inhabiting the land that God promised to Israel. So, God assured Joshua of success in conquering the land for Israel because He would be with Joshua wherever he went.
It’s almost like God was giving Joshua a pep talk before the battle started because three times in this passage God tells Joshua to “be strong and courageous” (vs. 6, 7, 9). And then God’s admonition to Joshua is repeated by the officers of Israel’s army to reinforce God’s command (vs. 18).
“So Moses said to them, “If you will do this, if you will arm yourselves before the Lord for the war, and all of you armed men cross over the Jordan before the Lord until He has driven His enemies out from before Him, and the land is subdued before the Lord, then afterward you shall return and be free of obligation toward the Lord and toward Israel, and this land shall be yours for a possession before the Lord” (Numbers 32:20-22, NASB).
After the forty years of wandering in the desert came to an end and the conquest of Canaan was about to begin, two of the Israelite tribes (Reuben and Gad) requested that they be allowed to settle in the fertile grazing land in Transjordan on the east side of the Jordan River: “If we have found favor in your sight, let this land be given to your servants as a possession; do not take us across the Jordan” (vs 5).
“For the battle is not yours, but God’s” (2 Chronicles 20:15, NLT).
When a vast army from Edom marched against Judah, King Jehoshaphat was frantic and pleaded with God for guidance. Jehoshaphat ordered the people of Judah to fast and pray.
People from all the towns of Judah gathered at the Temple in Jerusalem and Jehoshaphat led them in public prayer. The Spirit of God came upon one of the Levites in the gathering and these are the words he proclaimed to King Jehoshaphat and all the people of Judah.
“For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete.” (2 Corinthians 10:3-6, ESV).
In these verses Paul defends his apostolic ministry to the Corinthians. Paul indicates that there is a world war being waged for the souls of men and women. But, it’s a spiritual war not a physical one.
