1 Samuel 2:27-361 Samuel 2:27-36 details a prophecy against Eli and his house. One lineverse reads:
31 The time is coming when I will cut short your strength and the strength of your priestly house, so that no one in it will reach old age
The problem with this is the fact that Hophni and Phinehas, Eli's sons, both seem to reached old age:
Iirc, tradition holds that Samuel was 39 years old when Eli died¹, aged 98(corroborated by this?). Immediately after Samuel's introduced, we read of the wickedness of Eli's sons(1 Sam 2:11-17). God reinforces his this message through the child Samuel, so we know that the chronology's in order: Eli's sons were active priests in Samuel's early years, and therefore ~70 at their death. They clearly reached 'old age.'
So what are we to make of 1 Samuel 2:31?
EDIT: Abiathar's another descendant of Eli's that seems to've reached old age. He joined David at Adullam(1 Samuel 22:20–23) and was later desposed by Solomon(1 Kings 2:27).
¹if the 20 years of 1 Samuel 7:2 span the time from the Ark's return(and Eli's death) to David's 7th year and Samuel died at 52, then he was 39 at the time.
