창세기 13:8의 Musar

One must make great efforts to avoid personal strife. If a quarrel is in the offing, one must immediately strive to remove the cause of such quarrel, as our sages said in Sanhedrin 7 when commenting on Proverbs 17,14: פוטר מים ראשית מדון, "Starting a quarrel is like opening a sluice." Abraham demonstrated this virtue when he said to Lot: "let there not develop a quarrel between us." I detect a special meaning in Abraham employing the feminine form for the word strife, i.e. מריבה, although the Torah had already reported a "strong" quarrel, ריב, having occurred between their respective shepherds (Genesis 13,7). Abraham considered מריבה as a development of ריב. He considered the "fruit" of ריב to be מריבה. The latter word is akin to מתרבה, "constantly increasing." Since women produce children, he used the female form of the word ריב, i.e מריבה, in order to allude to the peculiarity of quarrels which keep increasing. He viewed ריב as something masculine, unable to give birth.
