'Sixty' in the Bible

and others fell upon the good ground, and yielded fruit, some a hundredfold, some sixty, some thirty.

And he that was sown upon the good ground, this is he that heareth the word, and understandeth it; who verily beareth fruit, and bringeth forth, some a hundredfold, some sixty, some thirty.

Here is wisdom. He that hath understanding, let him count the number of the beast; for it is the number of a man: and his number is Six hundred and sixty and six.
