John 13:23

Amplified Bible

²³^[a]One of His disciples, whom Jesus loved (esteemed), was ^[b]leaning against Jesus’ chest.

John 13:23 Probably John the Apostle, author of this Gospel and brother of James the Apostle. The mother of John and James was Salome, who is believed to be the sister of Mary, the mother of Jesus. If so, Jesus and the brothers were related as cousins.
John 13:23 As was customary in ancient times, everyone at the meal was reclining on his side on a long dining couch or bench. When there was a pause during the meal for discussion, it was common among close friends for one to lean back on the chest or shoulder of the other.
