Matthew Poole and continuators on Deuteronomy 28:66

66 And thy life shall hang in doubt before thee , and thou shalt fear day and night: and shalt have none assurance of thy life,

Either because thou art in the hands of thy enemies that have power, and want not will, to destroy thee▪ or because of the terrors of thy own mind, and the guilt of thy conscience making thee to fear, even where no great cause to fear is.
