Genesis 25:1 Now Avraham had taken another wife, her name was Keturah.
(יט) וַיָּ֤שָׁב אַבְרָהָם֙ אֶל־נְעָרָ֔יו וַיָּקֻ֛מוּ וַיֵּלְכ֥וּ יַחְדָּ֖ו אֶל־בְּאֵ֣ר שָׁ֑בַע וַיֵּ֥שֶׁב אַבְרָהָ֖ם בִּבְאֵ֥ר שָֽׁבַע׃ (פ)
(19) Abraham then returned to his servants, and they departed together for Beer-sheba; and Abraham stayed in Beer-sheba.

(9) Sarah saw the son whom Hagar the Egyptian had borne to Abraham playing. (10) She said to Abraham, “Cast out that slave-woman and her son, for the son of that slave shall not share in the inheritance with my son Isaac.” (11) The matter distressed Abraham greatly, for it concerned a son of his. (12) But God said to Abraham, “Do not be distressed over the boy or your slave; whatever Sarah tells you, do as she says, for it is through Isaac that offspring shall be continued for you. (13) As for the son of the slave-woman, I will make a nation of him, too, for he is your seed.” (14) Early next morning Abraham took some bread and a skin of water, and gave them to Hagar. He placed them over her shoulder, together with the child, and sent her away. And she wandered about in the wilderness of Beer-sheba.
(98) An angel appeared unto Sarah while she was in the presence of the king, to whom he was not visible, and he bade her take courage, saying, "Fear naught, Sarah, for God hath heard thy prayer." The king questioned Sarah as to the man in the company of whom she had come to Egypt, and Sarah called Abraham her brother. Pharaoh pledged himself to make Abraham great and powerful, to do for him whatever she wished. He sent much gold and silver to Abraham, and diamonds and pearls, sheep and oxen, and men slaves and women slaves, and he assigned a residence to him within the precincts of the royal palace. In the love he bore Sarah, he wrote out a marriage contract, deeding to her all he owned in the way of gold and silver, and men slaves and women slaves, and the province of Goshen besides, the province occupied in later days by the descendants of Sarah, because it was their property. Most remarkable of all, he gave her his own daughter Hagar as slave, for he preferred to see his daughter the servant of Sarah to reigning as mistress in another harem.

(4) And her name was Keturah: Rav said, "She is Hagar." Rabbi Nechemiah said to him, "And is it not written, 'he added.'" He said to him, "[That signifies that] he [now] married her according to the [Divine] word; like that which you say (Isaiah 8), 'And the Lord added to speak to me more.'" He said to him, "And is it not written, 'And her name was Keturah?'" He said to him, "[It is] since she was fragrant (mekuteret) with commandments and good deeds." He said to him, "And is it not written, 'And to the sons of the concubines that Avraham had?'" He said, "It is [actually] written, 'concubine' (in the singular, such that there only be one concubine - Hagar)." "While he was still alive (chai)" - [this is a reference to] the one that sat by the well and said to the Life (chai) of the worlds, "Look at my embarrassment!" Rabbi Berakhia said, "Even though you say (Genesis 21:14), 'and she went and strayed in the wilderness, etc., [such that] you would say that she was suspected with any [other man]; hence we learn to say, 'And her name was Keturah' - like a type of knot (ketur) like this, [with which] he seals a storehouse and opens it with a seal, [that is] tied and sealed." Bar Kapra said, "The addition of the Holy One, blessed be He, is greater than the main part:
