'Preserve' in the Bible

Come, let us make our father drink wine, and let us lie with him that we may preserve our family through our father.”

On the following day, the firstborn said to the younger, “Behold, I lay last night with my father; let us make him drink wine tonight also; then you go in and lie with him, that we may preserve our family through our father.”

Now do not be grieved or angry with yourselves, because you sold me here, for God sent me before you to preserve life.

God sent me before you to preserve for you a remnant in the earth, and to keep you alive by a great deliverance.

As for you, you meant evil against me, but God meant it for good in order to bring about this present result, to preserve many people alive.
