NASB
"and as they were returning, after spending the full number of days, the boy Jesus stayed behind in Jerusalem. But His parents were unaware of it,"
— Luke 2:43, NASB
“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. ”
“and when they had fulfilled the days, as they were returning, the boy Jesus tarried behind in Jerusalem; and his parents knew it not; ”
“and when they had fulfilled the days, as they were returning, the boy Jesus stayed behind in Jerusalem. Joseph and his mother didn't know it,”
“But when the feast was over, as they were returning home, the boy Jesus stayed behind in Jerusalem. His parents did not know it,”
“And having fulfilled the days, when they returned, the child Jesus remained in Jerusalem. And his parents knew it not.”
“And when the days of the feast came to an end and they were going back, the boy Jesus was still in Jerusalem, but they had no knowledge of it:”
“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. ”
The Child continued to grow and become strong, increasing in wisdom; and the grace of God was upon Him.
Now His parents went to Jerusalem every year at the Feast of the Passover.
And when He became twelve, they went up there according to the custom of the Feast;
and as they were returning, after spending the full number of days, the boy Jesus stayed behind in Jerusalem. But His parents were unaware of it,
but supposed Him to be in the caravan, and went a day's journey; and they began looking for Him among their relatives and acquaintances.
When they did not find Him, they returned to Jerusalem looking for Him.
Then, after three days they found Him in the temple, sitting in the midst of the teachers, both listening to them and asking them questions.
