Luke 2:40

38 And coming in that instant she gave thanks to¹ the Lord, and spoke of Him to all those who ^alooked for redemption in Jerusalem.

39 So when they had performed all things according to the law of the Lord, they returned to Galilee, to their own city, Nazareth.

40 ^aAnd the Child grew and became strong¹ in spirit, filled with wisdom; and the grace of God was upon Him.

41 His parents went to ^aJerusalem ^bevery year at the Feast of the Passover.

42 And when He was twelve years old, they went up to Jerusalem according to the ^acustom of the feast.

43 When they had finished the ^adays, as they returned, the Boy Jesus lingered behind in Jerusalem. And¹ Joseph and His mother did not know it;

44 but supposing Him to have been in the company, they went a day’s journey, and sought Him among their relatives and acquaintances.
