'Survivors' in the Bible

Now the Valley of Siddim was full of tar pits. When the kings of Sodom and Gomorrah fled, they fell into them, but some survivors fled to the hills.

One of the survivors came and told Abram the Hebrew, who lived near the oaks belonging to Mamre the Amorite, the brother of Eshcol and the brother of Aner. They were bound by a treaty with Abram.

God sent me [to Egypt] ahead of you to preserve for you a remnant on the earth, and to keep you alive by a great escape.
