'Noonday' in the Bible

“Your life would be brighter than noonday;Darkness would be like the morning.

He will bring forth your righteousness as the lightAnd your judgment as the noonday.

“Their widows will be more numerous before MeThan the sand of the seas;I will bring against them, against the mother of a young man,A destroyer at noonday;I will suddenly bring down on herAnguish and dismay.
