1347. Verse 18. And Peleg lived thirty years, and he begot Reu.
'Peleg lived thirty years' means the beginning of the fifth state, 'Peleg' having the same meaning here as previously. 'And he begot Reu' means a derivative from it, 'Reu' being a nation so named from him as its forefather which means worship even more external.
