Komentaryo sa Genesis 26:27: Or HaChaim, Radak & Rabbeinu Bahya

ויאמר אליהם יצחק, Issac said to them, etc. We have to understand why Isaac spoke to the king and his entourage in such a hostile manner. It seems incompatible with our image of Isaac. Besides, seeing that in the end he did make a covenant with them, what was the point of the hostile attitude Isaac displayed initially? Furthermore, once Isaac had told Avimelech and company that they hated him, why did he spell out how this hatred had expressed itself, i.e. by his being expelled from Gerar? If the latter sentence was meant to prove the Philistines' hatred of him, he should have said כישלחתם אותי, when you expelled me instead of ותשלחוני מאתכם, suggesting that they let him go unmolested?

ויאמר...ותשלחוני, the plural mode here indicates that at the time when Avimelech had expelled Yitzchok he had done so by following the advice of his ministers and notables. He had also said at that time “לך מעמנו,” Go from us!”

מדוע באתם אלי ואתם שנאתם אותי ותשלחוני מאתכם, “why do you come to me? You hate me and have driven me away from your midst!” Yitzchak reminded Avimelech and his chief of staff of three matters. 1) “why do you come to me?” He referred to the distance between Gerar and Beer Sheva where he now lived. 2) “You hate me” on account of my being successful and the vast numbers of cattle and sheep which I own. 3) You drove me away.” He referred to the district of Gerar where he had settled previously and Avimelech had told him “go away from us for you are too powerful for us” (26,16).
