Commentary for I Kings 2:22

וַיַּעַן֩ הַמֶּ֨לֶךְ שְׁלֹמֹ֜ה וַיֹּ֣אמֶר לְאִמּ֗וֹ וְלָמָה֩ אַ֨תְּ שֹׁאֶ֜לֶת אֶת־אֲבִישַׁ֤ג הַשֻּׁנַמִּית֙ לַאֲדֹ֣נִיָּ֔הוּ וְשַֽׁאֲלִי־לוֹ֙ אֶת־הַמְּלוּכָ֔ה כִּ֛י ה֥וּא אָחִ֖י הַגָּד֣וֹל מִמֶּ֑נִּי וְלוֹ֙ וּלְאֶבְיָתָ֣ר הַכֹּהֵ֔ן וּלְיוֹאָ֖ב בֶּן־צְרוּיָֽה׃ (פ)

And king Solomon answered and said unto his mother: ‘And why dost thou ask Abishag the Shunammite for Adonijah? ask for him the kingdom also; for he is mine elder brother; even for him, and for Abiathar the priest, and for Joab the son of Zeruiah.’
