1 Samuel 4:18 describes Eli's immediate death, whereas 1 Samuel 2:32 suggests he would see distress in the tabernacle before his descendants faced adversity.
1 Samuel 2:32: And thou shalt see an enemy [in my] habitation, in all [the wealth] which [God] shall give Israel: and there shall not be an old man in thine house for ever. [an enemy...: or, the affliction of the tabernacle, for all the wealth which God would have given Israel]

1 Samuel 4:18 recounts Eli's death at an old age, but 1 Samuel 2:33 discusses sparing one to weep over the house but not to live for old age.
1 Samuel 2:33: And the man of thine, [whom] I shall not cut off from mine altar, [shall be] to consume thine eyes, and to grieve thine heart: and all the increase of thine house shall die in the flower of their age. [in the flower...: Heb. men]
