'Physical' in the Bible

"This is the ordinance of the law that the LORD commanded that the Israelis be told: They are to bring you a spotless red heifer, without physical defect, that has never been fitted with a yoke.

The Egyptians are men, not God, and their horses are physical, not spirit. When the LORD stretches out his hand, anyone who assists will stumble, and the one who is helped will fall; and they will all perish together."

They were to be young men without physical defect, handsome in appearance, skilled in all wisdom, quick to learn, prudent in how they used knowledge, and capable of serving in the king's palace. They were to learn the literature and language of the Chaldeans.
