What is the name of the temple Jesus got lost in?
The temple was called Herod's Temple or the Herodian temple. It was built by Herod about 20 - 19 BC.
I think Jesus wasn't lost in the temple his parents left Jerusalem and Jesus was left behind he was found teaching in the temple. Read the verses below:
Luk 2:42 When Jesus was twelve years old, they went to the festival as usual.
Luk 2:43 When the festival was over, they started back home, but the boy Jesus stayed in Jerusalem. His parents did not know this;
Luk 2:44 they thought that he was with the group, so they traveled a whole day and then started looking for him among their relatives and friends.
Luk 2:45 They did not find him, so they went back to Jerusalem looking for him.
Luk 2:46 On the third day they found him in the Temple, sitting with the Jewish teachers, listening to them and asking questions.
Luk 2:47 All who heard him were amazed at his intelligent answers.
Jesus was not lost. When his parents were finished with their dealings in the city, they left with a large entourage, and assumed that Jesus was somewhere in the group. Jesus made His way to the Temple to teach what He knew. It was several days later that Mary and Joseph found Him at the temple expounding scriptures and teaching the elders. Jesus knew He was about His fathers' business. Not Joseph, but the business…
Jesus as a child worshiped in the temple with his parents, the bible says it was here thay he got lost and , was also found there. Jesus worshipped as a child the same as any Jewish child of the time - by attending the synagogue with his parents. In addition, He had a perfect understanding of the Jewish teachings since, as God, he was the originator of them.
