1 Samuel 2:31

I will cut off thine arm. The arm is the usual metaphor for strength. As Eli had preferred the exaltation of his sons to God's honour, he is condemned to see the strength of his house broken. Nay, more; there is not to be an "old man in his house." The young men full of energy and vigour perish by the sword; the Survivors fade away by disease. The Jews say that the house of Ithamar was peculiarly short-lived, but the prophecy was amply fulfilled in the slaughter of Eli's house, first at Shiloh, and then at Nob by Doeg the Edomite at the command of Saul. There is nothing to warrant an abiding curse upon his family. The third or fourth generation is the limit of the visitation of the sins of the fathers upon the children.
