Melachim Alef 14:21

21 And Rechav‘am Ben Sh’lomo reigned in Yehudah. Rechav‘am was forty and one years old when he began to reign, and he reigned seventeen years in Yerushalayim, the Ir which Hashem did choose out of kol Shivtei Yisroel, to put Shmo there. And shem immo was Naamah HaAmmonit (an Ammonitess).

Melachim Alef 14:21 Meaning and Commentary

1 Kings 14:21

And Rehoboam the son of Solomon reigned in Judah
Over the two tribes of Judah and Benjamin, when Jeroboam reigned over the other ten:

Rehoboam [was] forty one years old when he began to reign;
being born one year before his father Solomon began to reign, and so it might have been expected he would have begun his reign more wisely than he did:

and he reigned seventeen years in Jerusalem;
not half so long as his father and grandfather, being neither so wise nor so good a prince as either of them:

the city which the Lord did choose out of all the tribes of Israel, to
put his name there;
to have a temple built for him, and his worship carried on in it; which was an aggravation of the sin of Rehoboam, that he should reign in such a place, and yet be guilty of the crimes he was; the three first years he reigned well, but afterwards forsook the law of the Lord, ( 2 Chronicles 11:17 ) ( 12:1 )

and his mother's name was Naamah an Ammonitess;
and which is observed again, ( 1 Kings 14:31 ) , she being the instrument of drawing him into idolatry, which it is very probable she practised in the days of Solomon, ( 1 Kings 11:5 1 Kings 11:7 ) .

Melachim Alef 14:21 In-Context

19 And the rest of the acts of Yarov‘am, how he warred, and how he reigned, behold, they are written in the Sefer Divrei HaYamim L’Malkhei Yisroel.

20 And the yamim (days) which Yarov‘am reigned were two and twenty shanah; and he slept with his avot, and Nadav bno reigned in his place.

21 And Rechav‘am Ben Sh’lomo reigned in Yehudah. Rechav‘am was forty and one years old when he began to reign, and he reigned seventeen years in Yerushalayim, the Ir which Hashem did choose out of kol Shivtei Yisroel, to put Shmo there. And shem immo was Naamah HaAmmonit (an Ammonitess).

22 And Yehudah did the rah in the eyes of Hashem, and they provoked Him to kina (jealousy) with their chattot which they had committed, which were more than all that their avot had done.

23 For they also built them [idolatrous] high places, and matzevot (idol images), and Asherim [Canaanite female nature idols] on every high hill, and under every thickly foliaged green tree.
