The Levites must surround the king with weapons in hand, and anyone who enters the temple must be put to death. You must stay close to the king wherever he goes.”
We may well imagine the bad posture of affairs in Jerusalem during Athaliah's six years' usurpation, and may wonder that God permitted it and his people bore it so long; but after such a dark and tedious night the returning day in this revolution was the brighter and the more welcome.
Commenting on 2 Chronicles 23:1-11
And the Levites shall compass the king round about, every man with his weapons in his hand; and whosoever [else] cometh into the house, he shall be put to death: but be ye with the king when he cometh in, and when he goeth out. (d) Meaning to make any tumult, or to hinder their enterprise.
2Ch 23:7 “And the Levites shall compass the king round about, each with his weapons in his hand.” The Levites are the bodies of guards mentioned in 2Ch 23:4, 2Ch 23:5. If we keep that in view, then the following words, “every one who cometh into the house shall be put to death,” say the same as the words, “every one who cometh within the ranks” (2Ki 11:8).
