The Bible verse Mark 1:21 from the King James Version (KJV) reads, "And they went into Capernaum; and straightway on the sabbath day he entered into the synagogue, and taught."

This verse is from the Gospel of Mark, which is the second book of the New Testament. It is part of the larger narrative about the ministry of Jesus Christ, specifically at the beginning of his public ministry. In this verse, Jesus and his disciples are in Capernaum, a town in the northern part of Israel. It was a thriving center of commerce and culture, and it is where Jesus performed many miracles and taught his followers.

The first part of the verse mentions that they went into Capernaum. This sets the scene for the rest of the passage. It is important to note that Capernaum was a predominantly Jewish town, and Jesus and his disciples were observant Jews as well. The fact that they went into Capernaum and then straightway on the sabbath day entered into the synagogue shows Jesus' commitment to the Jewish religious practices. Despite any differences he may have had with the religious leaders of his time, Jesus remained committed to observing the Sabbath and participating in the synagogue worship.

The verse also highlights Jesus' role as a teacher. It mentions that he entered the synagogue and taught. This emphasizes the importance of teaching and passing on knowledge in the Jewish tradition. In this context, Jesus' teachings were likely focused on the scriptures and how they applied to everyday life. His teachings would have been rooted in the Hebrew Scriptures, or what Christians refer to as the Old Testament, and would have been interpreted in light of his own ministry.

This verse also shows Jesus' authority as a teacher. In the following verses, it is noted that the people were amazed at his teaching "for he taught them as one that had authority, and not as the scribes" (Mark 1:22, KJV). This demonstrates that Jesus' teaching was not merely informative, but it was authoritative and transformative. His teaching had a powerful impact on the people who heard him, and it set him apart from the religious leaders of his time.

The themes present in this verse include the importance of teaching and learning in the Christian faith. Jesus' role as a teacher is central to his ministry, and his teachings are a key aspect of the Christian message. Additionally, the verse emphasizes the observance of religious practices, such as the Sabbath and participation in synagogue worship. It underscores the continuity between Jesus' ministry and the Jewish religious tradition from which it emerged.

Symbolically, the synagogue represents a place of community and worship for the Jewish people. By entering the synagogue and teaching, Jesus is affirming the importance of communal worship and instruction in the faith. It also symbolizes Jesus' role as the fulfillment of the Jewish religious tradition. His teachings are rooted in the scriptures and carry forward the message of the Hebrew prophets.

In conclusion, the verse Mark 1:21 from the King James Version of the Bible provides insight into Jesus' ministry and his role as a teacher. It emphasizes the importance of teaching and learning in the Christian faith, as well as the continuity between Jesus' ministry and the Jewish religious tradition. The verse also highlights the authority of Jesus' teaching and the impact it had on those who heard it. As such, it holds significance for understanding the foundational aspects of the Christian faith and Jesus' role within it.
