In 1 Ki 6:1, the time between the Exodus and the fourth year of Solomon’s reign is 480 years. The cumulative time in Acts 13:18-22 totals 570 years for this period not including the four years for the beginning of Solomon’s reign (40 years for the wilderness journey, 450 years for the judges, 40 years for Saul and 40 years for David). There’s a big discrepancy here.

Is this an error? No. Paul’s time of the judges accounts for both the time of each judge including the peace resulting from his rule and the time of foreign oppression by a foreign adversary. These times actually overlap. In the table below, you see the 450 years of all the judges, the periods of rest and the years of foreign oppression. When you deduct the years of foreign oppression (marked in bold italics) you get a net of 336 years, since each judge is actually delivering Israel while the adversary is oppressing them.

This gives us the reconciliation between I Ki 6 and Acts 13. As you can see, there are no errors in your King James Bible.

To cross-check these dates though, we should do one other thing. It is typically thought that the Exodus took place in 1491 BC. If that’s so, then the temple construction began in 1011 BC, 480 years later (1 Ki 6:1).

The table below then dates the major events from the Exodus to the splitting of the 10 northern tribes from the 2 southern tribes at the beginning of Rehoboam’s reign.
