'Years' in the Bible

Now Eli [was] {ninety-eight years old} and his eyes {stayed fixed ahead} and he was not able to see.

Just as he mentioned the ark of God, he fell from his chair backwards against the side of the gate. He broke his neck and died, because the man was old and heavy. He had judged Israel forty years.

{From} the day the ark stayed in Kiriath Jearim, {days multiplied and became twenty years} while all the house of Israel mourned after Yahweh.

Saul [was thirty] {years old} at the beginning of his reign, and he reigned [forty-]two years over Israel.

Then the commanders of [the] Philistines said, "What [are] these Hebrews [doing here]?" And Achish said to the commanders of [the] Philistines, "Is this not David, the servant of Saul, the king of Israel, who has been with me {for days and years}? I have not found anything [threatening] in him from the day of his desertion until this day!"
