'Kept for Your Generations' in the Bible

And Moses said, This is the thing which Jehovah has commanded: Fill an omer of it to be kept for your generations, so that you may see the bread with which I have fed you in the wilderness, when I brought you forth from the land of Egypt.

And Moses said to Aaron, Take a pot and put an omer full of manna in it, and lay it up before Jehovah, to be kept for your generations.
