'Muscles' in the Bible

“When they (Israel) grasped you (Egypt) by the hand,You broke and tore apart their hands;When they leaned on you,You broke and strained their backs.”

I will put tendons on you and muscles over you and will cover you with skin; I will put breath in you and you will live. Then you will know that I am the Lord.'"

As I continued to watch, I saw tendons growing on the bones, and muscles growing and covering them, and then skin covered the flesh from above. But the bodies weren't breathing.
