In Exodus 23:15, Abib, the month equivalent to April in the Hebrew calendar, signifies the beginning of a new state. In that calendar, it was the first month. (Arcana Coelestia 9291)

The Passover, and with it, the beginning of the Exodus from Egypt, happened during Abib.

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.
