'Old' in the Bible

it is an old leprosy in the skin of his flesh; and the priest shall pronounce him unclean, and he shall not shut him up, for he is unclean.

Before the hoary head thou shalt rise up, and shalt honour the face of an old man; and thou shalt fear thy God: I am Jehovah.

and ye shall sow in the eighth year, and ye shall eat of the old fruit until the ninth year; until her produce come in, ye shall eat the old.

And ye shall eat old store, and clear away the old because of the new.

And thy valuation shall be of the male from twenty years old even unto sixty years old: thy valuation shall be fifty shekels of silver, after the shekel of the sanctuary;

And if it be from five years old even unto twenty years old, thy valuation of the male shall be twenty shekels, and for the female ten shekels.

And if it be from a month old even unto five years old, thy valuation of the male shall be five shekels of silver; and for the female thy valuation shall be three shekels of silver.

And if it be from sixty years old and above, if it be a male, thy valuation shall be fifteen shekels; and for the female ten shekels.
