The story of Ruth does not get added to our years, due to the statement in Ruth 1:1. The statement suggested Ruth occurred inside of the 410 years of Judges. I suspect Ruth and all the way to ISam9 is part of the 410 years of Judges. The people that ruled over Israel in the 410 years of Judges were not looked at as Kings. They were more like high priest and religious leaders. I suspect the 410 years ends when God Anoints His first King in ISam9. The first human King of Israel is Saul. It is after ISam8 that the social structure of Israel begins to change from the norm of Judges. So I will continue my time line from ISam9. ISam9 is actually the beginning of IKgs. These are the hits on "years" in ISam, IISam and IKgs. I removed any thing that was not needed for our calculations. It got a little tricky when I tried to follow the story line. So I had to key off of one bloodline, that would be David's.
1Sam:13:1: Saul reigned one year; and when he had reigned two years over Israel,
2 years
2Sam:5:4: David was thirty years old when he began to reign, and he reigned forty years.
2Sam:5:5: In Hebron he reigned over Judah seven years and six months: and in Jerusalem he reigned thirty and three years over all Israel and Judah.
40 years
1Kgs:11:42: And the time that Solomon reigned in Jerusalem over all Israel was forty years.
40 years
1Kgs:14:21: And Rehoboam the son of Solomon reigned in Judah. Rehoboam was forty and one years old when he began to reign, and he reigned seventeen years in Jerusalem, the city which the LORD did choose out of all the tribes of Israel, to put his name there. And his mother's name was Naamah an Ammonitess.
17 years
1Kgs:15:2: Three years reigned he in Jerusalem. And his mother's name was Maachah, the daughter of Abishalom.
3 years
1Kgs:15:10: And forty and one years reigned he in Jerusalem. And his mother's name was Maachah, the daughter of Abishalom.
41 years
1Kgs:22:42: Jehoshaphat was thirty and five years old when he began to reign; and he reigned twenty and five years in Jerusalem. And his mother's name was Azubah the daughter of Shilhi.
25 years
The years add up to be 168. We take that and add it to our 3270 years from our previous study.
3270 + 168 = 3438 years
