Arcana Coelestia # 1216
1216. 'According to their families' means according to their habits and customs, 'according to their tongues' means according to their individual beliefs, 'in their lands' means in general as regards such beliefs, and 'in their nations' in general as regards such habits and customs. This becomes clear from the meaning in the Word of each of these, namely family, tongue, land, and nation, for which see what has been stated above at verse 5.
