'Womb' in the Bible

Hallow unto me every firstborn, whatever breaketh open the womb among the children of Israel, of man and of cattle: it is mine.

that thou shalt offer unto Jehovah all that breaketh open the womb, and every firstling that cometh of cattle which is thine: the males shall be Jehovah's.

And it came to pass, when Pharaoh stubbornly refused to let us go, that Jehovah slew all the firstborn in the land of Egypt, both the firstborn of men and the firstborn of cattle: therefore I sacrifice to Jehovah all that breaketh open the womb being males; and every firstborn of my children I ransom.

All that openeth the womb is mine; and all the cattle that is born a male, the firstling of ox and sheep.
