What Does the 390 Mean?

There is no consensus on what the number 390 signifies. No suggestion persuades. And when in the light of the house of Judah, house of Israel is made out to be the northern kingdom alone, the number 390 defies all explanation. The prophet may well have envisaged such a wilderness age of punishment for his wicked compatriots, but no effort has succeeded in making a 390 year exile plausible.
