Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

In forty days the spies returned to the camp at Kadesh (see at Num 16:6), and reported the great fertility of the land ("it floweth with milk and honey," see at Exo 3:8), pointing, at the same time, to the fruit they had brought with them; "nevertheless," they added (כּי אפס, "only that"), "the people be strong that dwell in the land, and the cities are fortified, very large: and, moreover, we saw the children of Anak there." Amalekites dwelt in the south (see at Gen 36:12); Hittites, Jebusites, and Amorites in the mountains (see at Gen 10:15-16); and Canaanites by the (Mediterranean) Sea and on the side of the Jordan, i.e., in the Arabah or Ghor (see at Gen 13:7 and Gen 10:15-18).
