'Illegitimate' in the Bible

A person of illegitimate birth may not enter the assembly of the Lord; to the tenth generation no one related to him may do so.

When the Lord first spoke through Hosea, he said to him, "Go marry a prostitute who will bear illegitimate children conceived through prostitution, because the nation continually commits spiritual prostitution by turning away from the Lord."

They have committed treason against the Lord, because they bore illegitimate children. Soon the new moon festival will devour them and their fields.

But if you do not experience discipline, something all sons have shared in, then you are illegitimate and are not sons.
