P1381:1, 125:3.1It had been arranged that the Nazareth party should gather in the region of the temple at midforenoon on the first day of the week after the Passover festival had ended. This they did and started out on the return journey to Nazareth. Jesus had gone into the temple to listen to the discussions while his parents awaited the assembly of their fellow travelers. Presently the company prepared to depart, the men going in one group and the women in another as was their custom in journeying to and from the Jerusalem festivals. Jesus had gone up to Jerusalem in company with his mother and the women. Being now a young man of the consecration, he was supposed to journey back to Nazareth in company with his father and the men. But as the Nazareth party moved on toward Bethany, Jesus was completely absorbed in the discussion of angels, in the temple, being wholly unmindful of the passing of the time for the departure of his parents. And he did not realize that he had been left behind until the noontime adjournment of the temple conferences.
P1381:2, 125:3.2 The Nazareth travelers did not miss Jesus because Mary surmised he journeyed with the men, while Joseph thought he traveled with the women since he had gone up to Jerusalem with the women, leading Mary's donkey. They did not discover his absence until they reached Jericho and prepared to tarry for the night. After making inquiry of the last of the party to reach Jericho and learning that none of them had seen their son, they spent a sleepless night, turning over in their minds what might have happened to him, recounting many of his unusual reactions to the events of Passover week, and mildly chiding each other for not seeing to it that he was in the group before they left Jerusalem.
