Abimelech used this rhetorical question to accuse Abraham. AT: "You have done something bad to us!" or "Look what you have done to us!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
The word "us" here is exclusive and does not include Abraham and Sarah. If your language uses an exclusive form of "we" or "us," use it here. (See: [[rc://en/ta/man/translate/figs-exclusive]])
Abimelech used this rhetorical question to remind Abraham that he had not sinned against Abraham. AT: "I have done nothing against you to cause you to bring ... sin." (See: [[rc://en/ta/man/translate/figs-rquestion]])
To cause someone to be guilty of sinning is spoken of as if "sin" was a thing that could be placed on a person. AT: "that you should make me and my kingdom guilty of such a terrible sin" (See: [[rc://en/ta/man/translate/figs-metaphor]])
