'Old' in the Bible

“But how can anyone be born when he is old?” Nicodemus asked Him. “Can he enter his mother’s womb a second time and be born?”

The Jews replied, “You aren’t 50 years old yet, and You’ve seen Abraham?”

“I assure you: When you were young, you would tie your belt and walk wherever you wanted. But when you grow old, you will stretch out your hands and someone else will tie you and carry you where you don’t want to go.”
