'Heat of the Day' in the Bible

And Jehovah appeared unto him by the oaks of Mamre, as he sat in the tent door in the heat of the day;

And it was so on the morrow, that Saul put the people in three companies; and they came into the midst of the camp in the morning watch, and smote the Ammonites until the heat of the day: and it came to pass, that they that remained were scattered, so that not two of them were left together.

And the sons of Rimmon the Beerothite, Rechab and Baanah, went, and came about the heat of the day to the house of Ish-bosheth, as he took his rest at noon.
