'Sons' in the Bible

And James the son of Zebedee, and John the brother of James; and he surnamed them Boanerges, which is, The sons of thunder:

Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:

And James and John, the sons of Zebedee, come unto him, saying, Master, we would that thou shouldest do for us whatsoever we shall desire.
