Luke 2:41-52 - Jesus In The Temple At Twelve Years Old
41 Now his parents went to Jerusalem every year at the feast of the passover. 42 And when he was twelve years old, they went up to Jerusalem according to the custom of the feast. 43 And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not of it. 44 But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintances. 45 And when they found him not, they turned back again to Jerusalem, seeking him. 46 And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions. 47 And all that heard him were astonished at his understanding and answers. 48 And when they saw him, they were amazed: and his mother said unto him, Son, why have you thus dealt with us? behold, your father and I have sought you sorrowing.
51 And he went down with them, and came to Nazareth, and was subject unto them: but his mother kept all these sayings in her heart. 52 And Jesus increased in wisdom and stature, and in favor with God and man.
