'Womb' in the Bible

“See, I have taken the Levites from the Israelites in place of every firstborn Israelite from the womb. The Levites belong to Me,

For they have been exclusively assigned to Me from the Israelites. I have taken them for Myself in place of all who come first from the womb, every Israelite firstborn.

Please don’t let her be like a dead baby whose flesh is half eaten away when he comes out of his mother’s womb.”
