I. An exhortation to God's people not to be frightened at this threatening calamity, nor to be put into any confusion or consternation by it. Let the sinners in Zion be afraid (ch. xxxiii. 14): but O my people, that dwellest in Zion, be not afraid of the Assyrian, v. 24. Note, It is against the mind and will of God that his people, whatever may happen, should give way to that fear which has torment and amazement. Those that dwell in Zion, where God dwells and where his people attend him, and are employed in his service, that are under the protection of the bulwarks that are round about Zion (Ps. xlviii. 13), need not be afraid of any enemy. Let their souls dwell at ease in God.
