'Judgment seat' in the Bible

When Gallio was ruler of the country of Achaia, the Jews made insurrection with one accord against Paul, and brought him to the judgment seat,

When he had tarried there more than ten days he departed unto Caesarea, and the next day sat down in the judgment seat, and commanded Paul to be brought.

Then said Paul, "I stand at Caesar's judgment seat, where I ought to be judged. To the Jews have I no harm done, as thou verily well knowest.

But why doest thou then judge thy brother? Other why dost thou despise thy brother? We shall all be brought before the judgment seat of Christ.

For we must all appear before the judgment seat of Christ, that every man may receive the works of his body according to that he hath done, whether it be good or bad.
