Midrasch zu Bereschit 20:15

What is the meaning (of Prov. 27:10): A CLOSE NEIGHBOR IS BETTER THAN A DISTANT BROTHER? The Holy One said to Abimelech ben Jerubbaal (of Jud. 9): King Abimelech of the Philistines is better than you because he gave a lot of honor to Abraham, as stated (in Gen. 20:15): THEN ABIMELECH SAID: HERE BEFORE YOU IS MY LAND. Why did he say this? It is simply that he saw all the honor with which the Holy One had honored him, as stated (in Gen. 20:3): BUT GOD CAME UNTO ABIMELECH IN A DREAM AT NIGHT. He said to him (ibid.): You fool! HERE YOU ARE TO DIE BECAUSE OF THE WOMAN WHOM YOU HAVE TAKEN. You have all this happiness at hand, and you are dying on account of a woman! Did you not consider that (in ibid., cont.) SHE IS A MARRIED WOMAN (lit.: A HUSBAND'S WIFE)? What is the meaning of this HUSBAND'S (ba'al, rt.: B'L) WIFE (be'ulah, rt.: B'L)? {Is it not} [simply that] she is the mistress (ba'alah, rt.: B'L) of a {mistress} [husband] (ba'al, rt.: B'L)?
