'Neck' in the Bible

You must redeem every firstborn of a donkey with a flock animal, but if you do not redeem it, break its neck. However, you must redeem every firstborn among your sons.

You must redeem the firstborn of a donkey with a sheep, but if you do not redeem it, break its neck. You must redeem all the firstborn of your sons. No one is to appear before Me empty-handed.
