Why did God reprove Eli?

Answer

"In that day I will perform against Eli all things which I have spoken concerning his house: when I begin, I
will also make an end. For I have told him that I will judge his house for ever for the iniquity which he
knoweth; because his sons made themselves vile, and he restrained them not." 1 Sam. 3:12,13.
