'Lowlands' in the Bible

The king made silver in Jerusalem as common as stones, and cedar wood as plentiful as the sycamore-fig trees that are in the lowland.

He also built towers in the wilderness and dug many cisterns, for he had a great deal of livestock, both in the lowlands and in the plain. He also had farmers and vinedressers in the hill country and in the fertile fields, for he loved the soil.
