Numbers 11:8
And the people went about, and gathered it, and ground it in mills, or beat it in a mortar, and baked it in pans, and made cakes of it: and the taste of it was as the taste of fresh oil. And the people went about, and gathered it, and ground it in mills, or beat it in a mortar, and baked it in pans, and made cakes of it: and the taste of it was as the taste of fresh oil.
The people went about and gathered the manna and then ground it in mills or beat it in a mortar and baked it in pans and made cakes of it, so that it could be prepared in different ways before eating, and its taste was as the taste of fresh oil. It was the daily bread God rained from heaven as the healthy food He designed for Israel, heavenly food described as angels' food, given along with purest water out of the flinty rock. This belongs to God's leading of His people from Egyptian bondage through the wilderness to prove and try them after promising to be their God and take them as His peculiar treasure, with the covenant promise to put no disease upon them if they obeyed Him in all things. God did not prohibit Israel from eating meat but withheld it in great measure.
The gathering, grinding or beating, and baking was work God assigned for Friday as part of preparation day duties, making it a test of whether Israel would keep the Sabbath holy. When Israel was content with God's portion, manna was sweet and nourishing, but dissatisfaction made it loathsome to them, so that it did not satisfy them. The people murmured against Moses and against God, lusted for meat and longed to sit by the flesh pots in Egypt, wishing themselves back there and at times preferring slavery and even death to being deprived of meat.
Israel's indulgence of appetite in this wilderness account became the means by which Satan overthrew them, teaching that God is displeased when appetite is permitted to control. In anger God granted their demand and gave them flesh to gratify their lustful appetite, and the transgression brought a deadly plague, with great numbers dying in the act of eating the meat for which they had lusted while it was still between their teeth.
