David obtained an answer through the Urim and Thummim, which the high priest carried in the breast pocket of his ephod (cf. 1 Samuel 23:2; 1 Samuel 23:4; 1 Samuel 23:9). God no longer responded to Saul"s prayers ( 1 Samuel 28:15), but He did answer David"s ( 1 Samuel 30:8). David divided his troops into two groups as he had when he organized his attack against Nabal ( 1 Samuel 25:13). The many comparisons and contrasts between this chapter and chapter25 point out the differences between foolish Nabal and wise David. The Besor Brook is probably the Wadi el Arish, which flows west into the Mediterranean Sea a few miles south of Ziklag. This stream marked the southwestern border of the land that God had promised to Abraham"s descendants. [source][source][source]
