'Number' in the Bible

Since his days have been determined, the number of his months is known to you. You've set his limit and he cannot exceed it.

"The wicked person writhes in pain throughout his life, a number of years has been reserved for the ruthless.

What will they care for their household after them, when the number of his months comes to an end?"

"God is truly awesome, beyond what we know; the number of his years is unknowable.

You should know! After all, you had been born back then, so the number of your days is great!
