'Form' in the Bible

During the first year of Cyrus, king of Persia, in fulfillment of the message from the LORD spoken through Jeremiah, the LORD prompted Cyrus, king of Persia, to make this proclamation throughout his entire kingdom, which was also released in written form:

Furthermore, everyone who wishes to repatriate from any territory where he now resides is to receive assistance from his fellow residents in the form of silver, gold, equipment, and pack animals, in addition to voluntary offerings for the Temple of the God of Jerusalem.
