'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; that they may see the bread that I gave you to eat in the wilderness, when I brought you out of the land of Egypt.

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