I read 1 Samuel 11 on Bible Gateway. At the end of the chapter was a footnote.
1 Samuel 11:1 Masoretic Text; Dead Sea Scrolls gifts
Now Nahash king of the Ammonites oppressed the Gadites and Reubenites severely. He gouged out all their right eyes and struck terror and dread in Israel. Not a man remained among the Israelites beyond the Jordan whose right eye was not gouged out by Nahash king of the Ammonites, except that seven thousand men fled from the Ammonites and entered Jabesh Gilead. About a month later, 1 Nahash... then it goes into the siege of Jabesh Gilead.
During the time of the Judges Israel seemed to go through cycles. A judge led them, the judge died, the people turned to false idols, they fell prey to another people, they repented, and God appointed a new judge who led them out of oppression.
In 1 Samuel, Samuel led them out of Philistine oppression and their idolatry seemed to be in check. Then because of perversions of justice by Samuels sons the people decide they're tired of judges and want a king. To the reader, replacing theology with a monarchy seems incredibly foolish. However if the Ammonites have been wreaking havoc and God wasn't repelling them, it's no wonder they wanted a king.
The additional text referred to above indicates that Jabesh Gilead is not a new aggression but one that has already done considerable damage to two of the northern tribes. If idolatry is in check and the people are for the most part behaving, the Ammonite oppression doesn't fit the model of the period of the judges.
What does "Masoretic Text; Dead Sea Scrolls gifts" mean and is it reliable enough to add as pre 1 Sam 11 text? Your comments?
