Midrasz do Przysłów 26:18

Rabban Gamaliel said: "Ahasuerus was a fickle-minded king [and therefore did Esther invite Haman so that if she obtained permission to execute him she could have him nearby ready to kill him before the king retards]." Again said Rabban Gamaliel: "After all, we must still hear what the Median has said, as we are taught in the following Baraitha: R. Elazar of Media said: 'She had intended to make Haman jealous of Ahasuerus, and Ahasuerus jealous of Haman.'" Rabba said: "[To uphold] the passage (Prov. 26, 18) Before downfall goeth pride." Abaye and Raba both said: "She intended to do as it is written (Jer. 51, 39) When they are heated I will prepare their drinking feasts and will make them drunken." Rabba b. Abahu once found Elijah the prophet, and asked him: "What did Esther intend to do when she invited Haman?" and he answered: "As all Tanaim and all the Amoraim explained."

AND SARAH SAW THE SON OF HAGAR THE EGYPTIAN etc - Rabbi Shimeon bar Yohai said: Rabbi Akiva used to interpret this to his [Ishmael’s] shame, Rabbi Akiba lectured: AND SARAH SAW [THE SON OF HAGAR THE EGYPTIAN, WHOM SHE HAD BORNE TO AVRAHAM, MAKING SPORT.] Now 'making sport' refers to nothing else but sexual immorality, as in the verse, "The Hebrew servant, whom you have brought to us, came in to make sport of me. (Gen. 39:17). This teaches that Sarah saw Ishmael ravish maidens, seduced married women and dishonored them. R. Ishmael taught: This term 'making sport' refers to idolatry, as in the verse, "And the people sat to eat and drink and got up to make sport' (Exodus 32:6). This teaches that Sarah saw Ishmael build altars, catch locusts, and sacrifice them. R. Eleazar said: The term 'making sport' refers to bloodshed, as in the verse, "Let the young men, please, arise and make sport before us" (II Sam. 2:14) Rabbi Azariah said in Rabbi Levi’s name: Ishmael said to Isaac: 'Let us go and see our pieces in the field' and he would pick up the bow and shoot arrows, aiming in Itzchak's direction, while pretending to be playing (making sport), as it is written: "as a madman who casts fire-brands, arrows, and death; so is the man that deceives his neighbor, and said: 'I am just joking (making sport)'. And I [Rabbi Shimon bar Yochai] say that this is to be interpreted to the praise [of Ishmael]. This expression of making sport is only used as 'inheritance'. In the moment that Itzchak our father was born all were happy. Ishmael said to them: are you dumb? I am the first-born, I am going to receive double portion [of the inheritance], that from the answer of Sarah our mother to Avraham 'because the son of this maidservant will not inherit with my son, with Itzchak' you learn that he would not inherit 'with my son' - even if he wasn't Itzchak - and 'with Itzchak' - even if he wasn't my son. All the more so [this is true] 'with my son, with Itzchak'.
