'Lifetime' in the Bible

Two sons were born to Eber. One of them was named Peleg because the earth was divided during his lifetime, and the name of his brother was Joktan.

Zabad his son, Shuthelah his son, and Ezer and Elead were killed by men who were natives of Gath, because they came down to take their livestock.

"You have shed a lot of blood and fought great battles. You won't be building a house for my name, since you have shed so much blood on the earth in my sight. But look! A son born to you will live comfortably, because I will give him rest from all his enemies that surround him on every side, since his name will be "Solomon" - I will give peace and quiet for Israel during his lifetime.
