'Mid day' in the Bible

Now the sons of Rimmon the Beerothite -- Recab and Baanah -- went at the hottest part of the day to the home of Ish-bosheth, as he was enjoying his midday rest.

The Beloved to Her Lover: Tell me, O you whom my heart loves, where do you pasture your sheep? Where do you rest your sheep during the midday heat? Tell me lest I wander around beside the flocks of your companions!
