Adam Clarke on 1 Peter 2:23

But committed himself - Though he could have inflicted any kind of punishment on his persecutors, yet to give us, in this respect also, an example that we should follow his steps, he committed his cause to him who is the righteous Judge. To avoid evil tempers, and the uneasiness and danger of avenging ourselves, it is a great advantage in all such cases to be able to refer our cause to God, and to be assured that the Judge of all the earth will do right.

The Vulgate, one copy of the Itala, St. Cyprian, and Fulgentius, read, Tradebat autem judicanti se injuste; "He delivered himself to him who judged unrighteously;" meaning Pontius Pilate. Some critics approve of this reading, but it has not sufficient evidence to recommend it as genuine.
