'Old' in the Bible

And Moses was eighty years old, and Aaron eighty-three years old, when they gave the Lord's word to Pharaoh.

And Moses said, We will go with our young and our old, with our sons and our daughters, with our flocks and our herds; for we are to keep a feast to the Lord.

Everyone who is numbered, from twenty years old and over, is to give an offering to the Lord.

A beka, that is, half a shekel by the holy scale, for everyone who was numbered; there were six hundred and three thousand, five hundred and fifty men of twenty years old and over.
