What Happened to the Non Jews Who Died Before Jesus Came?

[Wyrd of Gawd]

And there was that part where Yahweh tells his followers to sacrifice their first born sons to him. Exodus 13:2. Yahweh wasn't always against Human sacrifice.

FWIW, if you read further down, families provided an appropriate animal sacrifice in place of sacrificing their human firstborn.

Exodus 13:11-13 NKJV:

11 “And it shall be, when the Lord brings you into the land of the Canaanites, as He swore to you and your fathers, and gives it to you, 12 that you shall set apart to the Lord all that open the womb, that is, every firstborn that comes from an animal which you have; the males shall be the Lord’s. 13 But every firstborn of a donkey you shall redeem with a lamb; and if you will not redeem it, then you shall break its neck. And all the firstborn of man among your sons you shall redeem.

That was the perfect extortion racket.  Whenever a couple had their first child they had to ransom it from the thug priests.  And they had to supply the thug priests with a steady income of animals and food.  It was the perfect racket that was written into the Ten Commandments in Exodus 34:19-20.
