Text of the Seating at the Last Supper Video
Archeologists have discovered mosaics from the time of Jesus that come from reclining tables in the first century. Did you know that the rabbis taught that Passover must be observed at a recling table to show that you are free? Free people eat reclining.
Passover would have been at a three-side reclining table such as we see here. The new testament says they reclined at the table. The beloved disciple leaned of Jesus' chest. So we have shown reclining tables like this to learn about Passover in the time of Jesus.
