וְצָד֣וֹק הַ֠כֹּהֵן וּבְנָיָ֨הוּ בֶן־יְהוֹיָדָ֜ע וְנָתָ֤ן הַנָּבִיא֙ וְשִׁמְעִ֣י וְרֵעִ֔י וְהַגִּבּוֹרִ֖ים אֲשֶׁ֣ר לְדָוִ֑ד לֹ֥א הָי֖וּ עִם־אֲדֹנִיָּֽהוּ׃
But Zadok the priest, and Benaiah the son of Jehoiada, and Nathan the prophet, and Shimei, and Rei, and the mighty men that belonged to David, were not with Adonijah.
From David to Destruction
We may add that the Adoniyahu debacle and our narrow escape from it illustrates a major theme of Sefer Melachim and Sefer Yirmiyahu. Adoniyahu nearly emerges as a king, due to the ill-advised neglect of the prophetic message of Natan HaNavi, whom Melachim I 1:8 specifically notes is not included in the effort to coronate Adoniyahu. A disastrous reign of Adoniyahu, in turn, is narrowly averted due to David HaMelech and Batsheva heeding the advice and intervention of Natan HaNavi.
Rashi
And all the leaders and the mighty men unlike Adoniah, as it is written (I Kings 1:8): “... and David’s mighty men were not with Adoniah.”
