3Then said Paul to him, "God will strike you, you whitewashed wall! Do you sit to judge me according to the law, and command me to be struck contrary to the law?" 4Those who stood by said, "Do you malign God`s high priest?" 5Paul said, "I didn`t know, brothers, that he was high priest. For it is written, `You shall not speak evil of a ruler of your people.`"
