'Self same' in the Bible

And ye shall not eat bread, and parched, and early groats of grain, till the self-same day till that ye brought an offering to your God: a law forever to your generations, in all your dwellings

And ye called in this self-same day a holy calling of Jehovah to you: any work of labor ye shall not do: a law forever in all your dwellings for your generations.

And any work ye shall not do in that self-same day, for it is a day of expiation, to expiate for you before Jehovah your God.
