'Warm' in the Bible

Now King David had become old, {advanced in years}, and they covered him with garments, but he was not warm.

His servants said to him, "Let them search for a young virgin for my lord the king, and let her stand before the king. Let her be of use for him, and let her lie in your lap that my lord the king may be warm."

Then he went up and lay upon the child and put his mouth on his mouth, his eyes on his eyes, and his palms on his palms. As he bent down over him, the flesh of the boy became warm.

They are picking salt herbs, the leaves of bushes, and [the] roots of broom trees to warm themselves.

Also if two lie together, {they can keep each other warm}. But how can one person be warm?

And it {becomes fuel for a human}, and he takes some of it and grows warm; also, he kindles a fire and bakes bread. Also, he makes a god and bows in worship; he makes himself an image and bows down to it!

He burns half of it in [the] fire; he eats meat over half of it; he roasts a roast and is satisfied. Also he grows warm and says, "Ah! I am warm! I see [the] fire!"

You have sown much but have harvested little. You have eaten without [being] satisfied; {you have drunk without being satiated}; you have worn clothes without [being] warm; the one who earns wages puts it in {a pouch with holes}.'

and one of you should say to them, "Go in peace, keep warm and {eat well}," but does not give them what is necessary for the body, what [is] the benefit?
