'Illegitimate' in the Bible

No one of illegitimate birth shall enter the assembly of the Lord; none of his descendants, even to the tenth generation, shall enter the assembly of the Lord.

They have dealt treacherously against the Lord,For they have borne illegitimate children.Now the new moon will devour them with their land.

But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons.
