Luke 4:20

‘And he closed the book, and gave it back to the attendant, and sat down, and the eyes of all in the synagogue were fastened on him.’

Having read the passage standing, a mark of respect for the Scriptures, He gave the scroll back to the Synagogue attendant and then sat down (probably in the special seat allocated) in order to preach. It was quite normal to speak sitting down. And all eyes in the Synagogue were fixed on Him ready for what He had to say. We are intended to sense the expectancy.
