"Beautiful Savior"

Lately, I've been reading the Psalms in the NKJV.  Recently, I read Psalm 45, in which verse 2 begins, "You are fairer than the sons of men...."  This recalled a similar line in the second verse of "Beautiful Savior":  "Jesus is fairer."  In the ESV, this part of Psalm 45 is translated as "You are the most handsome of the sons of men," which still has the same general idea as the hymn.  Psalm 45:2 may not be a direct source for "Beautiful Savior," but it's certainly a related passage.
