Deuteronomy 2:5 Meddle not with them; for I will not give you of their land, no, not so much as a foot breadth; because I have given mount Seir unto Esau for a possession.
Israel had come to the edge of the Promised Land again, now on the west side of the Jordan River and the Dead Sea. The Lord commanded them specifically not to meddle with or take the land of Edom (descendants of Esau). Furthermore, He also told them not to mess with Moab or Ammon (descendants of Lot). If God did not give it to you, and you have no command, do not try to take it. It will not end well for you. In this instance, Israel obeyed the Lord, and did not meddle with Edom, Moab, or Ammon. He doesn’t tell us why. Just don’t do it.
However, God did tell them to attack Sihon of the Amorites and take their land. Israel did obey, and the result was complete victory, for the Lord was with them and gave them victory over the Amorites and the land west of the Jordan. About the Amorites, God said, “Possess their land for I have given it to you.” These examples are a kind of summary of God’s Word to us as well: Receive what I have given; do not take what I haven’t given.
This is a wonderful lesson for us NT Christians. Receive with thanks the wonderful gifts and blessings of God and live joyfully with them; do not covet or try to grab what God has not given you. This is God’s “how-to manual” for true prosperity and real success. But this is easier said than done, for it takes the Spirit’s wisdom and self-control. Also, we complain that we don’t know what God is giving us and what He is not. No excuse. It’s all given in His Word. Learn it. One clue: seek His kingdom and His will and the things above. God will add the rest.
