'Noonday' in the Bible

[Say to the ruler] “Give us advice, make a decision [for Moab, king of Judah];Cast your shadow [over us] like night in the midst of noon;Hide the outcasts, do not betray the fugitive [to his pursuer].

And if you offer yourself to [assist] the hungryAnd satisfy the need of the afflicted,Then your light will rise in darknessAnd your gloom will become like midday.

We grope for a wall like the blind,We grope like those who have no eyes.We stumble at midday as in the twilight;Among those who are healthy we are like dead men.
