Fun facts about Isaac:
--Only one chapter (Gen. 26) devoted to Isaac as main character; in contrast to 12 full chapters for Abraham, 11 for Jacob, not including Joseph narrative.
And yet, Isaac:
--Only Patriarch never to spend one day outside of Canaan
--Only Patriarch to have only one wife
--Lives to 180--longer than Abraham (175) and Jacob (147)

Midrash Chad Shenati, discovered in the Cairo Genizah, criticizes Abraham for not praying for Sarah and praises Isaac for praying for Rebekah, and gives Rebekah pride of place in its homiletic exposition of the parasha. (See http://thetorah.com/a-monogamous-isaac-prays-for-his-barren-wife/)
ויעתר יצחק ליהוה לנכח [ ] בוא וראה דרכו [ש]לי[צחק] ?לא? כדרכו של אברהם אברהם נעקרה אש’ כמה שנים ו?ל?א ב[קש] [רח]מים עליה אבל אבינו יצחק כיוןשראה את הדדבר [ ] התחיל ובקש רחמים עליה
“Isaac entreated the lord on behalf of [his wife].” (Gen 25:21) Come and see:[9] the conduct [of] Isa[ac] is not like the conduct of Abraham. Abraham’s wife was barren[10] for many years and he did not ple[ad for mer]cy on her behalf. But when our forefather Isaac saw the matter, [ ] he began to plead for mercy on her behalf.[11]

(18) Isaac dug anew the wells which had been dug in the days of his father Abraham and which the Philistines had stopped up after Abraham’s death; and he gave them the same names that his father had given them. (19) But when Isaac’s servants, digging in the wadi, found there a well of spring water, (20) the herdsmen of Gerar quarreled with Isaac’s herdsmen, saying, “The water is ours.” He named that well Esek, because they contended with him. (21) And when they dug another well, they disputed over that one also; so he named it Sitnah. (22) He moved from there and dug yet another well, and they did not quarrel over it; so he called it Rehoboth, saying, “Now at last the LORD has granted us ample space to increase in the land.” (23) From there he went up to Beer-sheba. (24) That night the LORD appeared to him and said, “I am the God of your father Abraham. Fear not, for I am with you, and I will bless you and increase your offspring for the sake of My servant Abraham.” (25) So he built an altar there and invoked the LORD by name. Isaac pitched his tent there and his servants started digging a well.

(26) And Abimelech came to him from Gerar, with Ahuzzath his councilor and Phicol chief of his troops. (27) Isaac said to them, “Why have you come to me, seeing that you have been hostile to me and have driven me away from you?” (28) And they said, “We now see plainly that the LORD has been with you, and we thought: Let there be a sworn treaty between our two parties, between you and us. Let us make a pact with you (29) that you will not do us harm, just as we have not molested you but have always dealt kindly with you and sent you away in peace. From now on, be you blessed of the LORD!” (30) Then he made for them a feast, and they ate and drank. (31) Early in the morning, they exchanged oaths. Isaac then bade them farewell, and they departed from him in peace. (32) That same day Isaac’s servants came and told him about the well they had dug, and said to him, “We have found water!”
