This is a pretty short passage: After Abimilech, the next judge to lead Israel was a man named Tola. Judges tells us absolutely nothing about Tola, except that he “rose to save Israel” (verse 1), and that he led Israel for twenty-three years. It doesn’t even tell us who or what he saved Israel from.
There’s not much to say about a passage like this. Except that it’s nice that the Bible records each and every judge, even if it doesn’t devote a lot of space to some of them.
