the.com/last supper

means The final meal Jesus shared with his twelve apostles before his arrest and crucifixion, especially as a moment of foreboding and farewell.

from From the Gospel accounts (Matthew, Mark, Luke, John) describing the Passover meal Jesus ate with his disciples the night before his death — the one where he broke bread, said one of them would betray him, and instituted what became the Christian rite of communion. 'Supper' is just the old plain word for the evening meal, from Old French 'soper,' related to 'sup.' The phrase stuck in English as the standard name for the scene, cemented further by centuries of painters — Leonardo da Vinci's version being the one everyone pictures, whether they've opened a Bible or not.
