Should such a man as I flee? - Shall I, who am governor of the people, appointed both by God and the king, shall I betray my trust, and leave the flock without a shepherd? Shall I be a traitor, and abandon the office to which I am appointed? - No! Who, in my situation, with such responsibility, and such prospects, would go into the temple to save his life? I will not: I will stand at my post, and be ready to receive my enemies whensoever they come; so let Sanballat, Tobiah, and Geshem look to themselves.
Would go into the temple to save his life - Rather “could go into the temple and live.” For a layman to enter the sanctuary was a capital offence (see Numbers 18:7).
