'Years' in the Bible

At that time Eli was 98 years old, and his gaze was fixed because he couldn’t see.

When he mentioned the ark of God, Eli fell backward off the chair by the city gate, and since he was old and heavy, his neck broke and he died. Eli had judged Israel 40 years.

Time went by until 20 years had passed since the ark had been taken to Kiriath-jearim. Then the whole house of Israel began to seek the Lord.

Saul was 30 years old when he became king, and he reigned 42 years over Israel.
