'Generations' in the Bible

Moses said, "This is what the LORD has commanded: "Set aside one omer of it for future generations, so that they may see the food with which I fed you in the desert when I brought you out of the land of Egypt.'"

Then Moses told Aaron, "Take a jar, fill it with about one omer of manna, and place it in the LORD's presence, to be preserved throughout future generations."

It is to be a regular burnt offering throughout your generations at the doorway to the Tent of Meeting in the LORD's presence, where I'll meet with you to speak to you there.

and when Aaron sets up the lamps at twilight, he is to offer it as a continual incense offering in the LORD's presence throughout your generations.

Each year Aaron is to make atonement on its horns with the blood of the sin offering of atonement. He is to make atonement on it each year throughout your generations. It is most holy to the LORD."
