'Half brothers' in the Bible

While Jesus was still speaking to the large crowds, His mother and [half-] brothers were standing outside [of the large house. See 13:1] wanting to speak to Him.

Then Jesus' mother and [half-] brothers came and stood outside [i.e., of a large house. See Matt. 12:46-13:1]. They sent a message to Him, asking Him to come out to them.

Then Jesus' mother and [half-] brothers came to Him, but they could not get near Him because of the [large] crowd.

After this incident, Jesus, His mother, His [half-] brothers and His disciples went down to Capernaum [i.e., located on the north shore of Lake Galilee] and stayed there a few days.

Then Jesus' [half-] brothers said to Him, "You should leave here and go to Judea so your disciples [there] can see the [supernatural] deeds you are performing.

For even Jesus' [half-] brothers did not believe in Him [i.e., at that time].

But after His [half-] brothers had gone up to the Festival, Jesus also went up, but secretly instead of openly.

These men continued in united prayer [for the kingdom to come? See 1:6; Matt. 6:10] along with [certain] women, Mary the mother of Jesus and His [half-] brothers.
