Tola and Jiar were Judges

 Judges 10:1-5

After the time of Abimelek, a man of Issachar named Tola son of Puah, the son of Dodo, rose to save Israel. He lived in Shamir, in the hill country of Ephraim.  He led Israel twenty-three years; then he died, and was buried in Shamir.

He was followed by Jair of Gilead, who led Israel twenty-two years. He had thirty sons, who rode thirty donkeys. They controlled thirty towns in Gilead, which to this day are called Havvoth Jair. When Jair died, he was buried in Kamon.

These two were not military leaders. They judged Israel, respectively, for 23 and 22 uneventful years.

Why?

Two men from  Ephraim and Gilead became judges of Isreal. They were not described too much, we don't know how and why they were judges.

These two men until the end of their life these were nothing that could be recorded, it means their life nothing could remember. How about my life will be memorized.

How?

What I can give to this world when I leave this world?
