Abram is the son of Terah, and traces his lineage back to Shem, back to Noah, and back to Adam. His wife Sarai is "the daughter of my father but not the daughter of my mother” (Gen 20:12), so she's his half sister.
The both of them are in Egypt, and Abram presents her as his sister to the Pharaoh (Gen 12:10), which she goes along with at his command, and Pharaoh "takes her into his house", which causes God to punish the Pharaoh. It is said that this is done to protect Abram, so that instead of killing him and taking his wife, they will honor him. And if you read this without any context, it's possible that it will seem like Abram is cucking himself and giving out his wife to people who fuck her, in order to weaponize God against those people and cause them to have to pay him. But it seems that their transgression is not taking the woman intimately, but literally taking her into their house, which itself is not allowed because she is the wife of another man.
It kind of underscores the problem with reading the text with no context because you can easily get the wrong meaning out of it.
In either case, he does have a pattern of weaponizing God against people with his wife in this way, as he does the same thing again with Abimelech (Gen 20). And in order to avoid punishment, Abimelech has to pay Abraham (his name is changed by God at this point). The reason given this time is that Abraham thinks that the people under Abimelech live without fear of God.
When Abimelech is pleading with God that he didn't know about Sarah's marital status (her name is also changed now), God knows he didn't know and that He himself prevented Abimelech from sinning against him because of this. This does indicate and back up the idea that Sarah isn't actually getting banged by anyone, but it doesn't change that Abraham and Sarah both know that their victims will be thinking about banging her, that they will get privileges because the different rulers believe she is bangable, that they will get payments after the rulers find out the truth, and that God will be on their side in the matter.
It seems then that it's acceptable to wield God as a weapon against your enemies.
You'll have to forgive me as I'm obviously not an authority on these subjects and am new to these texts. But it does make me wonder why Protestants would prefer to navigate these confusing and perplexing details on their own.
