So David checked his men with these words, and didn't allow them to rise against Saul. Saul rose up out of the cave, and went on his way.
The hem or edge of a person’s garment in the ancient Near East made a statement about his or her social standing. A king’s hem was especially ornate and identified him as the king. [Note: See Milgrom, pp. 61-65.] By cutting off this piece of Saul’s robe, which Saul may have laid aside as he relieved himself (1 Samuel 24:3), David suggested that he could cut off Saul’s reign just as easily (cf. 1 Samuel 24:21). His act constituted mild rebellion against Saul’s authority. [Note: D. J. Wiseman, "Alalakh," in Archaeology and Old Testament Study, p. 128.]
