A.T. Robertson Commentary Matthew 8:11

"And I say unto you, that many shall come from the east and the west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven:" — Matthew 8:11 (ASV)

Sit down (ανακλιθησοντα). Recline at table on couches as Jews and Romans did. Hence Leonardo da Vinci's famous picture of the Last Supper is an anachronism with all seated at table in modern style.
