'Warm' in the Bible

Now king David was old and stricken in years; and they covered him with clothes, but he couldn't keep warm.

Therefore his servants said to him, "Let there be sought for my lord the king a young virgin: and let her stand before the king, and cherish him; and let her lie in your bosom, that my lord the king may keep warm."

He went up, and lay on the child, and put his mouth on his mouth, and his eyes on his eyes, and his hands on his hands. He stretched himself on him; and the flesh of the child grew warm.

You whose clothing is warm, when the earth is still by reason of the south wind?

Again, if two lie together, then they have warmth; but how can one keep warm alone?

He burns part of it in the fire. With part of it, he eats meat. He roasts a roast, and is satisfied. Yes, he warms himself, and says, "Aha! I am warm. I have seen the fire."

Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves from the power of the flame: it shall not be a coal to warm at, nor a fire to sit before.

You have sown much, and bring in little. You eat, but you don't have enough. You drink, but you aren't filled with drink. You clothe yourselves, but no one is warm, and he who earns wages earns wages to put them into a bag with holes in it."
