'Heat' in the Bible

saying, These last have spent but one hour, and thou hast made them equal unto us, who have borne the burden of the day and the scorching heat.

And when ye see a south wind blowing, ye say, There will be a scorching heat; and it cometh to pass.

But when Paul had gathered a bundle of sticks and laid them on the fire, a viper came out by reason of the heat, and fastened on his hand.

But the day of the Lord will come as a thief; in the which the heavens shall pass away with a great noise, and the elements shall be dissolved with fervent heat, and the earth and the works that are therein shall be burned up.

looking for and earnestly desiring the coming of the day of God, by reason of which the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?

They shall hunger no more, neither thirst any more; neither shall the sun strike upon them, nor any heat:

And men were scorched men with great heat: and they blasphemed the name of God who hath the power over these plagues; and they repented not to give him glory.
