"You rebuked nations. This refers to Amalek, as it is said (Numbers 24:20), 'Amalek was the first of the nations.' You destroyed the wicked. This refers to Esau, the wicked one, as it is said (Malachi 1:4), 'They will call them the border of wickedness.'

He committed five sins in one day: he had relations with a betrothed woman, committed murder, denied the resurrection of the dead, denied God's sovereignty, and showed contempt for the birthright. Their name shall be blotted out, as it is said (Exodus 17:14), 'I will utterly blot out the remembrance of Amalek.' Rabbi Levi said: It is written (Genesis 25:23), 'Two nations are in your womb.' What did [God] say to her [Rebecca]?

'Two governments are in your womb.' I reveal to you what is hidden: 'The first of the nations shall emerge from you,' as it is said (Jeremiah 2:3), 'Israel is the holy first fruits of his harvest.' Rabbi Elazar said in the name of Rabbi Yehoshua: God never needed to rely on an intimate relationship with a woman, except for that righteous woman [Rebecca], and even she was only through the medium of an angel.

Rabbi said in the name of Rabbi Yose: It was through the name of Noah's son that [Rebecca] was blessed. 'Two nations are in your womb' - I [God] made seventy nations from [Noah's three sons], as it is said (Genesis 10:19), 'These are the three sons of Noah, and from these the whole earth was populated.' How? Japheth had fourteen descendants, Gog and Magog had thirty, and Ham had thirty.

That makes seventy. (Genesis 10:5) 'From these the isles of the nations were separated.' 'And two nations are in your womb' - I will make from one [nation], seventy souls, and they will be fruitful and multiply. Another interpretation of 'two nations' is that one is proud of his wealth, and the other is proud of his royalty: Edom among the nations and Solomon among Israel." Another matter, two nations whose hatred is embedded in your womb, all hate Esau and all hate Jacob.

Another matter, two nations that hate each other. They will separate from your womb. From this, we learn that Jacob was born circumcised and uncircumcised. He is one of the thirteen who were born circumcised.

Adam, the first man, Seth, Enosh, Kenan, Mahalalel, Jared, Enoch, Methuselah, Lamech, Noah, Shem, Terah, Jacob, Joseph, Moses, Samuel, David, Isaiah, Jeremiah were all born circumcised. Adam was at the beginning of the creation of the Holy One, blessed be He, as it is stated, "And he begot in his likeness, after his image" (Genesis 5:3). Enoch, as it is stated, "And Enoch walked with God" (Genesis 5:24).

And it is stated, "Noah walked with God" (Genesis 6:9). Noah, as it is stated, "Noah was a righteous man" (Genesis 6:9). Shem, as it is stated, "These are the generations of Shem" (Genesis 11:10). Whoever had his name repeated was born circumcised, such as Shem, Shem, Noah, Noah, Terah, Terah.

Jacob, as it is stated, "And Jacob was a straightforward man" (Genesis 25:27). And it states, "Jacob, Jacob" (Genesis 46:2). Joseph, as it is stated, "These are the generations of Jacob, Joseph" (Genesis 37:2). This teaches us that he was born circumcised like him [Jacob].

Moses, as it is stated, "Moses, Moses" (Exodus 3:4). And it is stated, "And she saw that he was good" (Exodus 2:2). He was born circumcised. (Samuel I 3:10) (meaning Samuel IV, as it is written) Samuel, Samuel. Isaiah, as it is stated, "The Lord called me from the womb" (Isaiah 49:1).

Jeremiah, as it is stated, "Before I formed you in the belly I knew you" (Jeremiah 1:5). David, as it is stated, "A golden Psalm of David" (Psalms 16:1). And much will the young servant serve. Rav Huna said, "If he merited, he will serve, and if not, he will not serve."

And when David saw how Esau made Israel slaves, he said before the Holy One, blessed be He, "Rebuke the nations who seek to destroy me" (Psalms 44:6).
