Exodus 13:2

Consecrate to me all the firstborn . Whatever is the first to open the womb among the people of Israel , both of man and of beast , is mine.

“Consecrate to me every firstborn male. The first offspring of every womb among the Israelites belongs to me, whether human or animal.”

Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast : it is mine.
