What does the Bible say about Jesus' siblings?

According to John 7:5, Jesus had brothers and sisters who were raised with Him, yet they did not believe in Him during His ministry. This is significant because it shows that even those closest to Christ can fail to recognize His divine nature. Matthew 13 names His brothers, further confirming their existence. While some of His siblings later came to believe—such as James and Jude—many during His lifetime were unable to see His holiness and true identity due to humanity's depravity and sin.
