Melachim Alef 16:19 Meaning and Commentary

1 Kings 16:19

For his sins which he sinned in doing evil in the sight of the
Lord
In the former part of his life, as well as now:

in walking in the way of Jeroboam, and in his sin which he did to make
Israel sin;
worshipping the golden calves, which he might do while a captain of the chariots, and also since he usurped the crown, sacrificing to them by way of thanksgiving, for being in possession of the kingdom; and though his reign was so short, he might give plain and strong intimations that he should continue the worship of idols.

Melachim Alef 16:19 In-Context

17 And Omri withdrew from Gibeton, and kol Yisroel with him, and they laid siege to Tirtzah.

18 And it came to pass, when Zimri saw that the Ir was taken, that he went into the armon (palace, castle) of the Bais HaMelech, and he burned the Bais HaMelech over him with eish, and died.

19 For his chattot which he sinned in doing rah (evil) in the eyes of Hashem, in walking in the derech Yarov‘am, and in his chattat which he did, to make Yisroel to sin.

20 Now the rest of the acts of Zimri, and his kesher that he plotted, are they not written in the Sefer Divrei HaYamim L’Malkhei Yisroel?

21 Then were HaAm Yisroel divided into two parts: half of the people followed Tivni Ben Ginat, to make him Melech; and half followed Omri.
