Midrasch zu Bereschit 11:27

What is written above of the matter (in Exod. 3:4)? WHEN THE LORD SAW THAT HE HAD TURNED ASIDE TO LOOK, GOD CALLED UNTO HIM FROM THE MIDST OF THE THORN BUSH AND SAID: MOSES, MOSES! R. Abba bar Kahana said: Everyone whose name is doubled has a share in both worlds (i.e., this world and the world to come):⁶⁸Tanh., Exod. 1:18; Tanh. (Buber), Gen. 2:1, 6; Gen. R. 30:4; 38:12; Exod. R. 2:6. NOAH, NOAH (in Gen. 6:9); ABRAHAM, ABRAHAM (in Gen. 22:11); JACOB, JACOB (in Gen. 46:2); MOSES, MOSES (in Exod. 3:4); SAMUEL, SAMUEL (in I Sam. 3:10); and the text TERAH, TERAH (in Gen. 11:27). He said to them: Terah also is to have a share in both worlds, for our father Abraham did not die until he had received the good news about the fact that his father Terah had repented, as stated (in Gen. 15:15): YOU SHALL GO UNTO YOUR ANCESTORS IN PEACE. < Abraham > said to him: Should I go to my ancestors with whatever good works you have saved up for him?⁶⁹Cf. Tanh., Exod. 1:18, which reads: “With whatever good works2have saved up?” At that time the Holy One brought the good news and said to him: By your life, your father Terah has repented. His name is therefore doubled (in Gen. 11:27).

And Moses went, and returned unto Jethro his father-in-law. Prior to this is written: And when the Lord saw that he returned to see … and He said: “Moses, Moses” (Exod. 3:4). R. Abba the son of Kahana said: Everyone whose name is repeated in immediate succession experiences life in both worlds: Noah, Noah (Gen. 6:9); Abraham, Abraham (ibid. 22:11); Jacob, Jacob (ibid. 46:2); Moses, Moses (Exod. 3:4); Samuel, Samuel (I Sam. 3:10); Perez, Perez (Ruth 4:15). However, someone retorted: Is it not also written: These are the generations of Terah, Terah (Gen. 11:27). He replied: Even he had a portion in both worlds, for our patriarch Abraham was not buried until he was assured that his father, Terah, had repented, for it is said: But thou shalt go to thy fathers in peace (ibid. 15:15). Abraham said to the Holy One, blessed be He: Master of the Universe: Shall I go to my fathers, though I have stored up good deeds in this world? The Holy One, blessed be He, answered: Be assured: Thy father hath repented. Hence his name was repeated.
