Psalms 91:6

Nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday.

Nor for the pestilence that walketh in darkness. The pestilence both to the imagination appears, and actually is, of a more aggravated virulence in the night; because the sunlight and heat has a sanitary effect. The death-stroke which fell on Egyptian first-born at night passed over the Israelites without doing any hurt, because they were under the protecting bloodmark of God's covenant.

Nor for the destruction that wasteth at noon-day - a still more destructive plague than the previously mentioned "pestilence" of an ordinary kind: the same Hebrew is found in Deuteronomy 32:24 [ qeTeb (H6986)]
