Definition: 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].

Explanation: Okay, let’s break down that verse from Luke 2:43. It's a really important and slightly mysterious part of the story about Jesus’ birth. Here’s what it means in simple terms: The Basic Idea: “When they had fulfilled the days…” – This means after Jesus was born, the people were celebrating and moving on. They were finished with the period of his life. “…the child Jesus tarried behind…” – Jesus wasn't immediately going home to be welcomed. He stayed a little longer in Jerusalem. It’s like he was taking a break or exploring. “And Joseph and his mother knew not [of it]” – This is the key part. Joseph, Jesus' father, and his mother were not aware of this delay. They didn't know that Jesus was still in Jerusalem. What it Means on a Deeper Level: This verse highlights several things: Jesus’ Plan: The Bible describes Jesus as having a specific plan for his arrival – he would return to be with his family. This verse shows that the journey wasn’t over yet. Joseph's Care: Joseph was incredibly devoted to his son and his well-being. He likely worried about him, but didn’t know where he was. Mystery and God’s Purpose: It suggests a level of mystery surrounding Jesus' arrival. God knew something significant was happening, but the details weren't immediately known to anyone else. In short, it means Jesus was in Jerusalem for a little while longer after his birth, and Joseph and his mother didn't realize it. --- Do you want me to: Explain another verse?
