Q: I was not aware that the Israelites had to sacrifice their first born (I think it was specifically their first born sons.). Why?
So this serves as a reminder of the importance and place of God in the lives of his people. Everything that they have, really ultimately belongs to God. And this redeeming them back is a way of keeping that in the front of their minds. The other thing that this does is point forward to when God would send his own Son who would redeem all of humanity from sin, death and the devil. He did this on the cross. And so, we can see in these verses a kind of foreshadowing taking place.
Here is another question. I am reading Numbers 3:40 – 51 and I am confused. So is the Lord saying I will take the Levites in place of requiring all Israelites to give up their first born? Also is He saying that a collection of 5 shekels must be given?
