The only 'families should shelter-in-place to avoid dying' story in the Bible is the story of Passover.

"12‘For I will pass through the land of Egypt on that night, and will strike all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the Lord. 13Now the blood shall be a sign for you on the houses where you are. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt."

"26And it shall be, when your children say to you, ‘What do you mean by this service?’ 27that you shall say, ‘It is the Passover sacrifice of the Lord, who passed over the houses of the children of Israel in Egypt when He struck the Egyptians and delivered our households.’ ” So the people bowed their heads and worshiped. 28Then the children of Israel went away and did so; just as the Lord had commanded Moses and Aaron, so they did."
…
"29And it came to pass at midnight that the Lord struck all the firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the captive who was [h]in the dungeon, and all the firstborn of livestock. 30So Pharaoh rose in the night, he, all his servants, and all the Egyptians; and there was a great cry in Egypt, for there was not a house where there was not one dead."
