Exodus 13:15

And it happened, when Paraih (Pharaoh) qashah (rough / hard) hardly shalach (send) us go, that Yahawah () harag (kill) all the bakawar (firstborn) in the aratz (Earth/land) of Matzarayam (Egypt), both the bakawar (firstborn) of adam (man), and the bakawar (firstborn) of animal. Therefore I zabach (sacrifice) to Yahawah () all that patar (opens) the racham (womb), being zakarayam (males); but all the bakawar (firstborn) of my ban (son) I padah (redeem).’
