This Bible passage tells the most about Jesus’ childhood.

Luke 2:

27 That day the Spirit led him to the Temple. So when Mary and Joseph came to present the baby Jesus to the Lord as the law required, 28 Simeon was there. He took the child in his arms and praised God, saying, 29 “Sovereign Lord, now let your servant die in peace, as you have promised. 30 I have seen your salvation, 31 which you have prepared for all people. 32 He is a light to reveal God to the nations, and he is the glory of your people Israel!” 33 Jesus’ parents were amazed at what was being said about him. 34 Then Simeon blessed them, and he said to Mary, the baby’s mother, “This child is destined to cause many in Israel to fall, but he will be a joy to many others. He has been sent as a sign from God, but many will oppose him. 35 As a result, the deepest thoughts of many hearts will be revealed. And a sword will pierce your very soul.” 36 Anna, a prophet, was also there in the Temple. She was the daughter of Phanuel from the tribe of Asher, and she was very old. Her husband died when they had been married only seven years. 37 Then she lived as a widow to the age of eighty-four. She never left the Temple but stayed there day and night, worshiping God with fasting and prayer. 38 She came along just as Simeon was talking with Mary and Joseph, and she began praising God. She talked about the child to everyone who had been waiting expectantly for God to rescue Jerusalem. 39 When Jesus’ parents had fulfilled all the requirements of the law of the Lord, they returned home to Nazareth in Galilee. 40 There the child grew up healthy and strong. He was filled with wisdom, and God’s favor was on him. 41 Every year Jesus’ parents went to Jerusalem for the Passover festival. 42 When Jesus was twelve years old, they attended the festival as usual. 43 After the celebration was over, they started home to Nazareth, but Jesus stayed behind in Jerusalem. His parents didn’t miss him at first, 44 because they assumed he was among the other travelers. But when he didn’t show up that evening, they started looking for him among their relatives and friends. 45 When they couldn’t find him, they went back to Jerusalem to search for him there. 46 Three days later they finally discovered him in the Temple, sitting among the religious teachers, listening to them and asking questions. 47 All who heard him were amazed at his understanding and his answers. 48 His parents didn’t know what to think. “Son,” his mother said to him, “why have you done this to us? Your father and I have been frantic, searching for you everywhere.” 49 “But why did you need to search?” he asked. “Didn’t you know that I must be in my Father’s house?” 50 But they didn’t understand what he meant. 51 Then he returned to Nazareth with them and was obedient to them. And his mother stored all these things in her heart. 52 Jesus grew in wisdom and in stature and in favor with God and all the people.
