"'and those who despise Me will be held in little esteem'": We learn [from here] the humility of the Holy One, blessed be He: He did not say, "and those who despise Me I will curse," but rather "will be held in little esteem" - automatically. And with the honor of the righteous ones He was more exacting, as it says (Genesis 12), "and those that curse you, I will malign."
Ramban
AND BE THOU A BLESSING. You will be the blessing by whom people will be blessed, saying, “G-d make thee as Abraham.” To this He added that all families of the earth23Verse 3 here. will cite him in blessing, not just the people of his country alone. It may be that the expression, And in thee shall all the families of the earth be blessed,23Verse 3 here. means that they will all be blessed on his account.
Now this portion of Scripture is not completely elucidated. What reason was there that the Holy One, blessed be He, should say to Abraham, “Leave your country, and I will do you good in a completely unprecedented measure,” without first stating that Abraham worshipped G-d or that he was a righteous man, [and] perfect?24Above, 6:9. As was the case with Noah. Or it should state as a reason for his leaving the country that the very journey to another land constituted an act of seeking the nearness of G-d.25Psalms 73:28. This may indeed be an illuminating personal remark shedding light on Ramban’s journey, towards the end of his life, to the Land of Israel; the very journey constituted to him a religious experience of “seeking the nearness of G-d.” The custom of Scripture is to state, “Walk before Me,26Genesis 17:1. and hearken to My voice, and I will do good unto you,” as is the case with David27See I Kings 2:4. and Solomon,28Ibid., 3:13-14. as well as throughout the Torah: If ye walk in My statute;29Leviticus 26:3. And it shall come to pass, if thou shalt hearken diligently unto the voice of the Eternal thy G-d.30Deuteronomy 28:1. And in the case of Isaac, it says, For My servant Abraham’s sake.31Genesis 26:24. But there is no reason for G-d to promise [Abraham a reward merely] for his leaving the country.
However, the reason [for G-d’s promising Abraham this reward] is that the people of Ur of the Chaldees did him much evil on account of his belief in the Holy One, blessed be He, and he fled from them to go to the land of Canaan, tarrying for a time at Haran, whereupon the Eternal told him to leave these places as well and to fulfill his original intention that his worship be dedicated to Him alone and that he call upon people [for the worhip of] the Name of the Eternal in the Chosen Land. There He would make his name great, and these nations would bless themselves by him, not as they treated him in Ur of the Chaldees, where they abused and cursed him, put him in prison or in the fiery furnace. He further told Abraham that He will bless those who bless him, and if some individual will curse him, he will be cursed in turn.
This then is the meaning of this portion of Scripture. The Torah, however, did not want to deal at length with the opinions of idol worshippers and explain the matter between him and the Chaldeans in the subject of faith, just as it dealt briefly with the matter of the generation of Enosh32Above, 4:26. See also above in Seder Noach, Note 280. and their thesis concerning the idol-worship which they instituted.

Rabbeinu Yonah
With ten tests Abraham, our father, was tested - and he withstood them all: The first was 'Ur (which besides being a place name can also mean fire) Kasdim' - that Nimrod dropped him down into the fiery furnace and he was saved. And this is not explicit in the Torah and it is from the words of tradition. But we have a hint about this thing from the Torah; that before Parshat Lech Lecha Meartsekha ouMemoladetekha, Ur Kasdim is mentioned twice above [it], to make known that it was because of that test that he withstood that God, may He be blessed, promised him and brought him to the land [of Israel. This is] like we find with Noah. As at the beginning it is written (Genesis 6:8), "But Noah found favor in the eyes of the Lord," and afterwards in Parshat Eleh Toledot Noach that he was saved from the waters of the flood - [which indicates that it was] because he found favor in his eyes. And the second is that He commanded him to go out from his land and from his birthplace, and he did so. And the third is that is stated (Genesis 12:10), "And there was a famine in the land." And even though the Holy One, blessed be He, promised him and said to him (Genesis 12:3), "And all the families of the earth shall bless themselves by you”; when He brought the famine, he did not question His traits. The fourth is the taking of Sarah to Pharaoh. The fifth is the war of the four kings when he deployed [only] three hundred and eighteen men and trusted in the Holy One, blessed be He; and a miracle was done for him that he was saved and he saved his brothers and all of the property of Sedom and Ammorah. And he endured the events [accepting that it was] for his good and for his merit. The sixth is that he was ninety-nine when he circumcised the flesh of his foreskin [and] placed himself in danger due to his old age, and he was saved. The seventh is the taking of Sarah to Avimelekh. The eighth is when he sent Hagar and Yishmael away by the commandment of God. And [even] if 'the thing was bad in his eyes on account of his son,' he fulfilled the commandment. The ninth was the binding of Yitzchak his son, about which it is written (Genesis 22:12), "For now I know that you fear God.” And did He not know until now - and is not everything revealed and seen in front of Him? Rather when the thing is known to the creatures, the Holy One, blessed be He, calls it, "For now I know that you fear God." And it comes to inform us that [this showed] greater fear of Heaven than all of the other commandments in the Torah. Since with all the tests except for this, He did not say to him "that you fear God" - as this test was the greatest of all of them, since he took his son to bring him up as a sacrifice. The tenth was the burial of Sarah. As it was stated to him (Genesis 13:17), "Get up, walk about the land, through its length and its breadth, for I give it to you”; but when his wife died, he could not find a place to bury her until he bought it - and he did not question.
