(1.) The prophet must rebuke their fears, and advise them by no means to yield to them, but keep their temper, and preserve the possession of their own souls (v. 4): Take heed, and be quiet. Note, In order to comfort there is need of caution; that we may be quiet, it is necessary that we take heed and watch against those things that threaten to disquiet us. "Fear not with this amazement, this fear, that weakens, and has torment; neither let thy heart be tender, so as to melt and fail within thee; but pluck up thy spirits, have a good heart on it, and be courageous; let not fear betray the succours which reason and religion offer for thy support." Note, Those who expect God should help them must help themselves, Ps. xxvii. 14.
