And the Lord said to Samuel: Look not on his countenance, nor on the height of his stature: because I have rejected him, nor do I judge according to the look of man: for man seeth those things that appear, but the Lord beholdeth the heart.
Adam Clarke
Man looketh on the outward appearance - And it is well he should, and confine his looks to that; for when he pretends to sound the heart, he usurps the prerogative of God. In what way were these communications made from God to Samuel? It must have been by direct inspirations into his heart. But what a state of holy familiarity does this argue between God and the prophet! I believe Moses himself was not more highly favored than Samuel.
