During the Israelites' 40 year exodus from slavery in Egypt to the Promised Land of Canaan, God provided them with quail every evening and bread (manna) Monday through to Saturday. There was always the perfect amount for each day and if anyone didn't trust God, and collected too much, it became rancid. However, double provision of manna was given on the 6th day, to be used towards the 7th day as well. This meant that the Israelites could have this final day of the week as a day of rest. These instructions were requests from God for the absolute good of the Israelites as He knew what was best for them (Exodus 16). The same instructions apply to us now! Do we hold on to excess provisions which end up becoming "rancid" in our lives? Do we trust God for His daily provision and even with the times of rest He wants to bless us with?
