'Kingdom' in the Bible

The beginning of his kingdom was Babel and Erech and Accad and Calneh, in the land of Shinar [in Babylonia].

Then Abimelech called Abraham and said to him, “What have you done to us? And how have I offended you that you have brought on me and my kingdom a great sin? You have done to me what ought not to be done [to anyone].”
