'Previous' in the Bible

Later on, a famine swept through the land. This famine was different from the previous famine that had occurred earlier, during Abraham's lifetime. So Isaac went to Abimelech, king of the Philistines, at Gerar.

but afterward seven years of famine and hunger will come, and [there will be such desperate need that] all the great abundance [of the previous years] will be forgotten in the land of Egypt [as if it never happened], and famine and destitution will ravage and destroy the land.

The previous abundance of the land will not be remembered because of the famine that follows, for the famine will be very severe.
