'Womb' in the Bible

"I'm taking the descendants of Levi for myself from among the Israelis in place of every first-born who opens the womb. The descendants of Levi belong to me

since they've been set apart for me from among the Israelis. I've taken them for myself instead of the first to open the womb every firstborn of the Israelis,

Everything that opens the womb, any living thing that they bring to the LORD whether from human beings or animals are for you. Just be sure that you redeem the firstborn of people and the firstborn of unclean animals.
