Introduction: One of my habits, which I believe is generally a good one, is that I am often thinking ahead. If I’m driving my car, I try to anticipate problems in the road ahead. If I’m walking in an area in which there might be danger, I consider what I will do if a problem arises. When I’m litigating a case, I always try to anticipate how the other side intends to argue. This habit has sometimes created problems, if only in my mind. If I come to the conclusion that someone wants to harm me, then I imagine what I will do in response. In 1 Timothy 6:4 the Bible discusses the person who creates problems based, among other things, on “evil suspicions.” That is exactly how my mind works sometimes; I imagine problems where likely none exist. Our study this week shows that I’m not the only one who has to be careful about evil surmising. Let’s leap into our study of the Bible and learn more!

I. The Division

A. Read Joshua 22:1-4. Do you recall what we studied about the two and a half tribes that wanted to settle on the east side of the Jordan River (the side opposite Jericho)? (They did not want to cross over the Jordan because the land on their side was great for cattle,  and they had cattle.)

1. When Joshua 22:3 refers to forsaking brothers and keeping the charge, to what does that refer? (Joshua 1:14-15 reviews the past agreement. The two and a half tribes can claim the land on the east side of the Jordan River as their land if they agree to cross the Jordan with the others and fight to conquer the land promised to all the tribes.)
2. Have the two and a half tribes kept their promise? (Yes! They have done as promised and are now crossing back over the Jordan to the land promised to them.)

B. Read Joshua 22:5-6. What final reminder does Joshua give the two and a half tribes before he blesses them and sends them on their way? (To love and obey God. To live a life that is consistent with obedience, and do it wholeheartedly.)

1. Is that the goal of your life? The goal you suggest for your children?

II. Alleged Treachery

A. Read Joshua 22:9-10. What would you conclude if you were present and saw this huge altar built by the two and a half tribes?

1. Could you sacrifice on such an altar? (Likely not. If it is huge, you could not reach the top except with a ladder.)
2. If an altar is not built to sacrifice to God, then is it intended to serve another god?
3. What would be the reason for building it, if not to sacrifice to the true God?

B. Read Joshua 22:11-12. Whoa! What has happened at lightning speed? (They are gathered for war! This huge altar was built on the west (Jericho) side of the river, according to the ESV and NIV translations.)

1. If this placement is true, for whom is it a message? (It would seem to be a message for the other tribes, not a stranger who has just passed through the land of the two and a half tribes.)

C. Look again at Joshua 22:12. Why are the rest of the tribes planning to go to war? (Because the two and a half tribes had built an altar.)

1. What did they think was wrong with that?

D. Let’s read on, Joshua 22:13–15. Let’s just stop here. Phinehas is leading the delegation of the tribes. Why is he leading? (Read Numbers 25:5-8. If you want someone serious about stopping idol worship, Phinehas is your man!)

E. Read Joshua 22:16-18 to continue following the confrontation. What is apparently wrong with building this altar? (The other tribes thought it was part of idol worship. They thought the two and a half tribes would be using it to offer sacrifices to another god.)

1. The people have a good sense of history; they refer to the “sin of Peor.” What is that? (That is the idol worship where Phinehas played a leading role in stopping it. This makes clear why the tribes chose Phinehas to confront the two and a half tribes.)

F. Read Numbers 25:1-3. The background for the “sin of Peor” is found in Numbers chapters 22-24. The Moabites were very concerned about the Israelites as they approached the Promised Land. So the Moabite King Balak asked the prophet Balaam to curse the Hebrews. That did not work. So Balak got advice from Balaam that instead of trying to beat the Hebrews militarily, they should try to lead them into sin. This resulted in the Moabite women seducing the Hebrew men into temple prostitution involving Baal. That worked for a while. A plague broke out. And Phinehas brought the episode to a violent end. With Phinehas leading, would this be a no-nonsense meeting?

G. Read Joshua 22:19-20. The people have a good memory. What is it they fear might happen to them if the two and a half tribes are involved in idol worship? (All the tribes would be punished.)

1. Do you think this concern is justified?

H. Look again at Joshua 22:18 where it says that “tomorrow [God] will be angry with the whole congregation of Israel.” Is it true today that sin affects the entire church? (Yes. Sin is contagious. Sin is demoralizing.)

1. In our church today we find some sloppy thinking. We start with the true premise that we are all sinners. From that, some conclude that because we all sin, we should welcome sinners who demand that the church accept their sin. What is the logical problem with this argument? (Promoting sin and teaching others to accept sin is far different than acknowledging our sinful state.)

III. The Conversation

A. Let’s read what the two and a half tribes said in response to these charges. Read Joshua 22:21–23. Do all the tribes agree on the nature of the sin of idol worship? (Yes. There is no theological dispute.)

B. Read Joshua 22:24-25. Does this seem to be a reasonable fear? That the descendants of the rest of the tribes might tell the children of the two and a half tribes that they were not allowed to worship the true God?

1. Let’s step back and discuss evil surmising. Were the main tribes engaged in evil surmising against the two and a half tribes when they saw the huge altar?
2. Were the two and a half tribes engaged in evil surmising when they thought their children would be prevented from worshiping the true God by the rest of the tribes? (I think the answer to both these questions is “Yes.” This problem arose because of evil surmising on both sides.)

C. Read Joshua 22:26-28.  We earlier discussed what could be the purpose of a huge altar on which sacrifices were not made. What purpose do the two and a half tribes have for building it? (It is a sign, a symbol, a witness that the two and a half tribes believe in sacrificing to the true God.)

D. Read Joshua 22:29. When people in the church accuse you of wrongdoing, or engage in evil surmising against you, how do you react?

1. How would you grade the reaction of the two and a half tribes? (It was exactly right. I can imagine some thinking, “The last thing Joshua warned us about was idol worship, and now the rest of the tribes are accusing us of the same thing.” It might make you oversensitive about the subject and cause a less than gentle response.)

E. Read Joshua 22:30-31 and Joshua 22:33-34. What results from this “almost war” situation? (It was a renewal of commitment to the true God. The huge altar, as intended, was a “Witness” that “the Lord is God.”)

F. What lessons do you see in getting along with one another in church? (1. Don’t assume the worst. 2. Discuss it. Do not pick up your weapons first. 3. When someone accuses you of something, be kind.)

G. Read Psalm 133:1. What can you do to promote this goal in your church?

H. Friend, if you want peace in your church, determine not to assume the worst about others. When problems arise, talk them out. Like me, work on avoiding evil surmising. Will you agree to this?
