Deuteronomy 23:1 states that no castrated man or eunuch may enter the assembly of the Lord, whereas Isaiah 56:3-5 explicitly promises that faithful eunuchs will receive a place and a permanent name within God's house. Traditional harmonization resolves this by explaining that Deuteronomy establishes a historical standard of ritual purity under the Mosaic Law, while Isaiah foretells a future prophetic era when these ceremonial exclusions are lifted for those who keep the covenant; conversely, critical scholarship views the tension as evidence of an ideological shift from the exclusive priestly codes of the Torah to a more inclusive theological framework in later prophetic traditions.
