Albert Barnes on John 19:13

Judgment-seat. The tribunal or place of pronouncing sentence. He came here to deliver him, in due form of law, into the hands of the Jews.

Pavement. This was an area or room of the judgment-hall whose floor was made of small square stones of various colours. This was common in palaces and houses of wealth and splendour. Mt 9:2.

Gabbatha. This word is not elsewhere used. It comes from a word signifying to be elevated. The name given to the place by the Hebrews was conferred from its being the place of the tribunal, as an elevated place.

(n) "When Pilate therefore heard" Prov 29:25, Acts 4:19
