In Leviticus we read about Moses (via God’s instruction) commanding the people of Israel with respect to various feasts/festivals and other procedures. I have always wondered where the people, after leaving Egypt got the required olive oil (for the lamp), grain (for normal eating as well as the commanded Holy Bread) among other things to keep God’s commands. I realize that they could have traded for these things but after 40 years of wandering in the wilderness what did they have left to trade?
