'Bones' in the Bible
They are not to leave any of it to remain until morning nor are they to break any of its bones. They are to observe it according to all the statutes of the Passover.
Whoever is out in an open field and touches the body of someone who was killed by a sword, or a dead body, or someone's bones, or a grave, he is to be considered unclean for seven days.
A clean person is to take some hyssop, dip it in water, and then sprinkle it on the tent, on every vessel, and on whoever was there (that is, on whoever touched the bones, the killed person, or the dead body, including whoever dug the grave).
God is bringing them out of Egypt with the strength of an ox. He'll devour enemy nations, break their bones, and impale them with arrows.
