Judges 10:1-5, Why so little information about these two judges?

Question: Why so little information about the 2 judges in vs 1-5? Answer: Only God can answer this fully of course, but here is my thought... Verse 6 says "Then the children of Israel again did evil". Perhaps Tola and Jair are mentioned to explain the timing, that Israel did not turn away right after Gideon, Tola and Jair helped keep Israel serving the Lord. After they died Israel turned to idolatry again. -PJ
