2 Samuel 21:2

The way in which the writer here refers to the history of the league with the Gibeonites Joshua 9 shows that the Book of Joshua was not a part of the same work as the Books of Samuel.

Of the Amorites - The Gibeonites were Hivites Joshua 9:7; Joshua 11:19; and in many enumerations of the Canaanite nations the Hivites are distinguished from the Amorites. But “Amorite” is often used in a more comprehensive sense, equivalent to “Canaanite” (as Genesis 15:16; Deuteronomy 1:27), and denoting especially that part of the Canaanite nation which dwelt in the hill country Numbers 13:29; Deuteronomy 1:7, Deuteronomy 1:20, Deuteronomy 1:24, and so includes the Hivites.
