'Six' in the Bible

On six days do all your work:

If one of your countrymen, a Hebrew man or woman, becomes your servant for a price and does work for you six years, in the seventh year let him go free.

Let it not seem hard to you that you have to send him away free; for he has been working for you for six years, which is twice the regular time for a servant: and the blessing of the Lord your God will be on you in everything you do.

For six days let your food be unleavened bread; and on the seventh day there is to be a holy meeting to the Lord your God; no work is to be done.
