'Safekeeping' in the Bible

And he said to them, "This is what Yahweh has said. Tomorrow [is] a rest period, a holy Sabbath for Yahweh. Bake what you [want to] bake, and boil what you [want to] boil. Put aside all the surplus for yourselves for safekeeping until the morning."

And Moses said, "This is the word that Yahweh has commanded. 'A full omer of it [is] for safekeeping for your generations so that they will see the bread that I fed you in the desert when I brought you from the land of Egypt.'"

And Moses said to Aaron, "Take one jar and put there a full omer of manna. Leave it before Yahweh for safekeeping for your generations."

As Yahweh had commanded Moses, so Aaron left it before the testimony for safekeeping.
