'Noonday' in the Bible

Rechab and Baanah, the sons of Rimmon the Beerothite, left and arrived during the hottest part of the day at the home of Ish-bosheth while he was taking a noon day nap.

They meet with darkness in broad daylight; at noonday they grope around as if it were night.

Your life will be brighter than noonday. Even its darkness will be like dawn.

He will bring forth your righteousness as a light, and your justice as the noonday sun.

if you pour yourself out for the hungry and satisfy the needs of afflicted souls, then your light will rise in darkness, and your night will be like noonday.
