Melachim Bais 11:4 Meaning and Commentary

2 Kings 11:4

And the seventh year Jehoiada sent and fetched the rulers over
hundreds, with the captains and the guard
This was the husband of Jehosheba, who was high priest, ( 2 Chronicles 22:11 ) these

rulers over hundreds
were not those appointed over the people for civil affairs, as by the advice of Jethro, but over the priests and Levites in their courses; five of whom are mentioned by name, and were employed in gathering together the Levites, and the chief of the fathers, throughout all the cities of Judah, ( 2 Chronicles 23:1 2 Chronicles 23:2 ) , and the "captains" here are the heads of the fathers there, who were the heads of the courses they were sent to gather; and the "guard", those of the late king, whom Athaliah had turned out of their post, and took in others in their room, unless rather the temple guard is meant:

and brought them to him into the house of the Lord;
the temple, that part of it where was the court of the priests and Levites:

and made a covenant with them;
to join with him, assist him, and stand by him in the restoration of the king, and the reformation of the kingdom:

and took an oath of them in the house of the Lord;
to keep secrecy, and be faithful to him:

and showed them the king's son;
for the truth of which he could produce his wife, the sister of the late king, and also the nurse of this child with him.

Melachim Bais 11:4 In-Context

2 But Yehosheva Bat HaMelech Yoram, achot Achazyahu, took Yoash ben Achazyahu, and stole him from among the Bnei HaMelech which were being slain; and they hid him, even him and his nurse, in the cheder hamittot (bedroom) from Atalyah, so that he was not slain.

3 And he was with her hid in the Beis Hashem shesh shanim. And Atalyah did reign over HaAretz.

4 And the seventh year Yehoyada sent and got the commanders of hundreds, with the Kereti and [Peleti] bodyguard [of HaMelech] and brought them to him into the Beis Hashem, and made a Brit with them, and put them under oath in the Beis Hashem, and showed them the Ben HaMelech.

5 And he commanded them, saying, This is the thing that ye shall do; a third part of you that come on duty on Shabbos shall even be Shomrei Mishmeret Bais HaMelech (Guards on duty at the Royal Palace);

6 And a third part shall be at the Sha’ar Sur; and a third part at the Sha’ar behind the ones guarding: so shall ye keep shomer the mishmeret HaBais for defense.
