'Six' in the Bible

At the end of seven years ye shall let go every man his brother, a Hebrew, who hath sold himself unto thee; when he hath served thee six years, thou shalt let him go free from thee. But your fathers hearkened not unto me, neither inclined their ear.

in the twenty-third year of Nebuchadrezzar, Nebuzar-adan the captain of the body-guard carried away captive of the Jews seven hundred and forty-five persons: all the persons were four thousand six hundred.
