'Sons' in the Bible

You are doing the works of your father. They said to him, We are true sons of Abraham; we have one Father, who is God.

In so far as you have the light, put your faith in the light so that you may become sons of light. With these words Jesus went away and for a time was not seen again by them.

Simon Peter, Thomas named Didymus, Nathanael of Cana in Galilee, the sons of Zebedee, and two others of his disciples were all together.
