C. F. Keil and Franz Delitzsch on Genesis 22:5-8

Gen 22:5-8

When in sight of the distant mountain, Abraham left the servants behind with the ass, that he might perform the last and hardest part of the journey alone with Isaac, and, as he said to the servants, “worship yonder and then return.” The servants were not to see what would take place there; for they could not understand this “worship,” and the issue even to him, notwithstanding his saying “we will come again to you,” was still involved in the deepest obscurity. This last part of the journey is circumstantially described in Gen 22:6-8, to show how strong a conflict every step produced in the paternal heart of the patriarch. They go both together, he with the fire and the knife in his hand, and his son with the wood for the sacrifice upon his shoulder. Isaac asks his father, where is the lamb for the burnt-offering; and the father replies, not “Thou wilt be it, my son,” but “God (Elohim without the article - God as the all-pervading supreme power) will provide it;” for he will not and cannot yet communicate the divine command to his son. Non vult filium macerare longa cruce et tentatione (Luther).
