'Flesh' in the Bible

And the ravens brought him bread and meat in the morning, and bread and meat in the evening; and he would drink from the brook.

So Elisha left him and went back. Then he took a pair of oxen and sacrificed them and boiled their meat with the implements of the oxen [as fuel], and gave the meat to the people, and they ate. Then he stood and followed Elijah, and served him.

Now when Ahab heard these words [of Elijah], he tore his clothes, put on sackcloth and fasted, and he lay in sackcloth and went about dejectedly (mourning).
