'Heat' in the Bible

For he will be like a tree planted by water, and to [the] stream it sends its roots, and it will not fear when heat comes, and its leaves will be luxuriant, and in [the] year of drought it will not be anxious, and it will not cease from the bearing of fruit.

{Therefore} thus says Yahweh concerning Jehoiakim, the king of Judah, "There will not be for him [one who] sits on the throne of David. And his dead body will be thrown out to the heat in the day and to the frost in the night.
