'Sin Against' in the Bible

Then Abimelech called Abraham in and said to him, “What have you done to us? How did I sin against you that you have brought such enormous guilt on me and on my kingdom? You have done things to me that should never be done.”

No one in this house is greater than I am. He has withheld nothing from me except you, because you are his wife. So how could I do such a great evil and sin against God?”
