'This Very Day' in the Bible

Then Aaron said to Moses, “This very day they have [obediently] presented their sin offering and their burnt offering before the Lord, but [such terrible things] as these have happened to me [and to them]; if I [and my sons] had eaten a sin offering today would it have been acceptable and pleasing in the sight of the Lord?”

You must not eat bread, roasted grain, or any new grain until this very day, and until you have brought the offering to your God. This is to be a permanent statute throughout your generations wherever you live.

"'On this very day you must proclaim an assembly; it is to be a holy assembly for you. You must not do any regular work. This is a perpetual statute in all the places where you live throughout your generations.
