'Thirty' in the Bible

Taken counsel have all the presidents of the kingdom, the prefects, and the satraps, the counsellors, and the governors, to establish a royal statute, and to strengthen an interdict, that any who seeketh a petition from any god and man until thirty days, save of thee, O king, is cast into a den of lions.

then they have come near, yea, they are saying before the king concerning the king's interdict: 'Hast thou not signed an interdict, that any man who seeketh from any god and man until thirty days, save of thee, O king, is cast into a den of lions?' Answered hath the king, and said, 'The thing is certain as a law of Media and Persia, that doth not pass away.'

O the blessedness of him who is waiting earnestly, and doth come to the days, a thousand, three hundred, thirty and five.
