You shall eat the tithe (tenth) of your grain, your new wine, your oil, and the firstborn of your herd and your flock before the Lord your God in the place where He chooses to establish His Name (Presence), so that you may learn to fear [and worship] the Lord your God [with awe-filled reverence and profound respect] always.

An Ammonite or Moabite shall not enter the assembly of the Lord; none of their descendants, even to the tenth generation, shall ever enter the assembly of the Lord,
