וְעָשִׂ֣יתִי אֹ֠תָם לְג֨וֹי אֶחָ֤ד בָּאָ֙רֶץ֙ בְּהָרֵ֣י יִשְׂרָאֵ֔ל וּמֶ֧לֶךְ אֶחָ֛ד יִֽהְיֶ֥ה לְכֻלָּ֖ם לְמֶ֑לֶךְ וְלֹ֤א יהיה־[יִֽהְיוּ־] עוֹד֙ לִשְׁנֵ֣י גוֹיִ֔ם וְלֹ֨א יֵחָ֥צוּ ע֛וֹד לִשְׁתֵּ֥י מַמְלָכ֖וֹת עֽוֹד׃
At gagawin Ko silang iisang bansa sa lupain, sa mga bundok ng Israel, at iisang hari ang maghahari sa kanilang lahat; at hindi na sila magiging dalawang bansa, at hindi na sila mahahati pa kailanman sa dalawang kaharian.

The first introduction in the matters of the kings memorialized in this book and it appropriate that we discuss ten topics: The first topic is the ??? according to their dates. For of the kings mentioned in these books, only a few ruled the whole nations: Shual, David, and Solomon who reigned over all the tribes united. You will see that all three were Men of Valor, G-d fearing and Men of Truth. As I explained in the Book of Samuel that the reigns summed to 100 years, keep this memory aid to hand (Kings 1, 20:31) "Magnanimous kings are they" for 'Melchi' adds to 100. These kings were unique in reigning over all the tribes without divisions because once the kingdom was divided in the days of Rechavem and Yeravam. King Rechavam and all the progeny of House of David ruled over the tribes of Yehuda and Binyamin, majority of the tribe of Levi and the fraction of the tribe of Shimon whose patrimony was amid the patrimony of the sons of Yehuda. You will see in their stories, which of them walked in peace and wealth along the path of their father, David and which among them ?betrayed? G-d and went wayward to serve other gods. The length of the reign of the Kings of Judah, good and bad, was 393 years. A hint to this (Proverbs 15:3) "The eyes of G-d observe both bad and good, since the words 'raim and tovim' sum to 393 [translator's note: the gemateria is 392 +1 for the phrase]

And a time to sew. [As it is stated,] “And they will become united in your hand;”19Yechezkeil 37:17. [and] “neither shall they be divided any longer into two kingdoms.”20Ibid. Verse 22.
