He looked on Amalek. This looking must have been an inward vision, because the haunts of the Amalekites were far away (see on Genesis 36:12; Exodus 17:8; Numbers 14:25, Numbers 14:45). The first of the nations.
Amalek was in no sense a leading nation, nor was it a very ancient nation. It was indeed the very first of the nations to attack Israel, but it is a most arbitrary treatment of the words to understand them in that sense.
The prophet Amos (Amos 6:1) uses the same expression of the Jewish aristocracy of his day. As it was in no better position than Amalek to claim it in any true sense, we can but suppose that in either case there is a reference to the vainglorious vauntings of the people threatened; it would be quite in keeping with the Bedawin character if Amalek gave himself out be "the first of nations."
