Final answer:
God provided the Israelites with manna and on one occasion quail in the desert for sustenance. The laws given to Moses in the Old Testament prohibited the consumption of both pork and shrimp, classifying them as unclean.
Step-by-step explanation:
The Israelites were provided with manna by God when they were in the desert, according to the biblical narrative. While manna is often considered the primary source of sustenance, there was also an occasion where God sent quail for meat to the Israelites.
As such, both manna and quail were miraculously provided during the Israelites' journey in the desert, but manna was the main food that sustained them on a daily basis. In reference to the laws God gave to Moses, neither eating pork nor eating shrimp would be consistent with those laws, as outlined in the Old Testament.
Specifically, the book of Leviticus details dietary restrictions that classify both pork and shrimp as unclean and therefore not permissible for consumption by the Israelites.
