'Six' in the Bible

(Only Og king of Bashan was left of the remnant of the Rephaim. His bed was made of iron. Isn’t it in Rabbah of the Ammonites? It is 13 feet six inches long and six feet wide by a standard measure.)

Six days thou shalt labour, and do all thy work:

And if thy brother, an Hebrew man, or an Hebrew woman, be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee.

It shall not seem hard unto thee, when thou sendest him away free from thee; for he hath been worth a double hired servant to thee, in serving thee six years: and the LORD thy God shall bless thee in all that thou doest.

Six days thou shalt eat unleavened bread: and on the seventh day shall be a solemn assembly to the LORD thy God: thou shalt do no work therein.
