Deuteronomy 23:3  (King James Version)
An Ammonite or Moabite shall not enter into the congregation of the LORD; even to their tenth generation shall they not enter into the congregation of the LORD for ever:
 


Ammonite
These nations were subjected for their impiety, wickedness, and enmity to Israel, (ver. 4, 5,) to peculiar disgrace; and on this account were not permitted to hold any office among the Israelites. This did not, however, disqualify them from becoming proselytes; for Ruth, who was a Moabitess, was married to Boaz, and became one of the progenitors of our Lord.
