Eat
When we eat, our bodies break down the food and get from it both energy and materials for building and repairing the body. The process is similar on a symbolic level in the Bible. Food represents the desire for good and the insight that comes from that desire for good – goodness and understanding that come from the Lord. But to put them to use we have to take them in and make them our own – which is spiritual eating.
Nations
'Nations,' as in Jeremiah 25:31, signify falsities. In Genesis 25:23, 'two nations in the womb' signify the natural regarding interior and exterior good. In general, 'nations' signify people in the good of love and charity from the Lord.
