'Womb' in the Bible

And I, behold, I have taken the Levites from among the children of Israel instead of every firstborn that breaketh open the womb among the children of Israel, and the Levites shall be mine;

For they are wholly given unto me from among the children of Israel; instead of every one that breaketh open the womb, instead of every firstborn among the children of Israel, have I taken them unto me.

Let her not be as one stillborn, half of whose flesh is consumed when he comes out of his mother's womb.

Everything that breaketh open the womb of all flesh, which they present to Jehovah, of men or of beasts, shall be thine; nevertheless the firstborn of man shalt thou in any case ransom, and the firstborn of unclean beasts shalt thou ransom.
