Could it be Clearer?
The Scottish Declaration of Independence, a prized document attested by Robert the Bruce's barons in Parliament assembled, dated A.D.1320, asserts that the nation of the Scots - with a king-list of one hundred and thirteen monarchs - moved to the British Isles from Scythia by way of Spain. The document emphasises an Israelite context to the effect that the migration occurred "1200 years after the outgoing of Israel" (from Egypt). This would indicate a period of the 3rd-2nd centuries B.C.
