Religious claim 1 – god exists
Religious claim 2 – god is just
Religious claim 3 – the Jews are god’s chosen people
Religious claim 4 – god let his chosen people suffer as slaves under the Egyptians for about 400 years
Now name the crime that the Jews committed that is justly punished by 400 years of slavery.
If you cannot name the crime, consider re-evaluating the claims.
In my view, which fits other sets of claims and observations:
Claim 1 is false and thus claim 2, claim 3, and claim 4 are false.
