1 Samuel 4:15

Eli was ninety and eight years old. Until the invention by the Arabs of the present system of numerals, all ancient nations had a most cumbrous system of expressing numbers. The Hebrew method was to attach a value to each of the letters of the alphabet, and then add them together, and thus the eighth and nineteenth letters would between them make up ninety-eight. Such a system led to constant mistakes in copying, and thus the numerals in the earlier parts of the Old Testament are beset with uncertainty. Here the Septuagint has ninety, and the Syriac seventy-eight. But as Eli was described already as "very old" in 1 Samuel 2:22 , the Hebrew text is the most probable. Instead of dim the Hebrew has set, i.e. Eli was now absolutely blind, as the word expresses the motionless state of the eye when obscured by cataract. In 1 Samuel 3:2 a different word is used, rightly there translated "dim," as the disease is one which comes on gradually. In I Kings 1 Samuel 14:4 we read that Ahijah was blind from the same cause, and the word is there correctly rendered "set."
