'Old' in the Bible

“The Lord possessed me at the beginning of His way,Before His works of old.

Grandchildren are the crown of old men,And the glory of sons is their fathers.

The glory of young men is their strength,And the honor of old men is their gray hair.

Train up a child in the way he should go,Even when he is old he will not depart from it.

Listen to your father who begot you,And do not despise your mother when she is old.
