In Jesus' day the custom in the synagogues was to stand for the reading of the Scripture and to sit down for the teaching of it, Lk. 4:16, 20; Mat. 5:11. The official synagogue-attendant handed the scroll of Isaiah to Jesus, which He unrolled and read from Isaiah 6:1-2 and Isaiah 58:6. When He finished reading He gave the scroll back to the attendant. As far as we know Jesus read the Scripture in Hebrew and translated it into Aramaic, the common spoken language of the people at that time.
