'Womb' in the Bible

'And I, lo, I have taken the Levites from the midst of the sons of Israel instead of every first-born opening a womb among the sons of Israel, and the Levites have been Mine;

For they are certainly given to Me out of the midst of the sons of Israel, instead of him who openeth any womb -- the first-born of all -- from the sons of Israel I have taken them to Myself;

let her not, I pray thee, be as one dead, when in his coming out from the womb of his mother -- the half of his flesh is consumed.'

every one opening a womb of all flesh which they bring near to Jehovah, among man and among beast, is thine; only, thou dost certainly ransom the first-born of man, and the firstling of the unclean beast thou dost ransom.
