וַיְצַ֣ו הַמֶּ֗לֶךְ אֶת־בְּנָיָ֙הוּ֙ בֶּן־יְה֣וֹיָדָ֔ע וַיֵּצֵ֕א וַיִּפְגַּע־בּ֖וֹ וַיָּמֹ֑ת וְהַמַּמְלָכָ֥ה נָכ֖וֹנָה בְּיַד־שְׁלֹמֹֽה׃
Lalu raja memberi perintah kepada Benaya anak Yoyada. Benaya keluar dan menyerang Simei sampai ia mati. Demikianlah kerajaan itu kokoh di tangan Salomo.
Rashi
The kingdom was thus established, etc. I.e., he was not punished for all these [actions].
