C. F. Keil and Franz Delitzsch on 2 Kings 11:15

2Ki 11:15

Jehoiada then commanded the captains החיל פּקדי, those placed over the army, i.e., the armed men of the Levites, to lead out Athaliah between the ranks, and to slay every one who followed her, i.e., who took her part (המת, inf. abs. instead of imperative); for, as is added supplementarily in explanation of this command, the priest had (previously) said: “Let her not be slain in the house of Jehovah.” The temple was not to be defiled with the blood of the usurper and murderess.
