'Brethren' in the Bible

After this he went down to Capernaum, he, and his mother, and his brethren, and his disciples; and there they abode not many days.

His brethren therefore said unto him, Depart hence, and go into Judaea, that thy disciples also may behold thy works which thou doest.

For even his brethren did not believe on him.

But when his brethren were gone up unto the feast, then went he also up, not publicly, but as it were in secret.

Jesus saith to her, Touch me not; for I am not yet ascended unto the Father: but go unto my brethren, and say to them, I ascend unto my Father and your Father, and my God and your God.

This saying therefore went forth among the brethren, that that disciple should not die: yet Jesus said not unto him, that he should not die; but, If I will that he tarry till I come, what is that to thee?
