Midrash su Isaia 43:1

... Jeremiah said: when I was coming up to Jerusalem, I lifted up my eyes and saw a woman sitting on the mountaintop, her clothes were black and her hair unkempt. She cried: I am seeking who will comfort me! And I cried: I am seeking who will comfort me! I came near and spoke with her, and I said to her: if you are a woman, then speak with me. If you are a spirit, then go away from me. She answered and said to me: Do you not recognize me? I am the one who had seven children. Their father went away to a land across the sea and as I was going up to cry for him, a prophet said to me ‘the house collapsed on your seven children and killed them.’ I do not know for whom I am crying and for whom my hair is unkempt.I answered and said to her: you are no better than my mother Zion, who was made a pasture for the beasts of the field. She answered and said to me: I am your mother Zion, I am she – the mother of seven, so it is written “She who bore seven has been cut off…” (Jeremiah 15:9) Jeremiah said to her: the blows you have received are like those of Job. Job’s sons and daughters were taken from him, your sons and daughters were taken from you. From Job I took his silver and gold, from you I have taken your silver and gold. I cast Job into the trash heap, you I have made into a heap of trash. And just as I came back and consoled Job, so too in the future I will return and console you. I doubled Job’s sons and daughters, and in the future I will double your sons and daughters. I doubled Job’s gold and silver, and in the future I will do so for you. I shook the trash from Job, and of you it is said “Shake yourselves from the dust, arise, sit down, O Jerusalem…” (Isaiah 52:2) Flesh and blood built you and flesh and blood destroyed you. But In the time to come I will build you, because thus it is written “The Lord is the builder of Jerusalem; He will gather the outcasts of Israel.” (Psalms 147:2) Amen! May the Holy One fulfill what is written about us speedily and in our day “And the redeemed of Zion shall return, and they shall come to Zion with song, with joy of days of yore shall be upon their heads; they shall achieve gladness and joy, and sadness and sighing shall flee.” (Isaiah 35:10)

Another explanation. “See, I have called by name Bezalel the son of Uri …” (Shemot 31:2) This is one of the seven people called by multiple names. There are those that were called by four names, which is Eliyahu, Bezalel had six, Yehoshua six, Moshe seven, Mordecai two, Daniel five, Hananiah, Mishael and Azariah had four. Eliyahu had four: R’ Elazar ben Padat said ‘Eliyahu was from Jerusalem and was among those who sat in the Court of Hewn Stones. He was from the city of Yehudah and his portion was in two tribal lands – five in Benyamin, as it says “And Zelah, Eleph, and the Jebusite, which is Jerusalem…” (Yehoshua 18:28) and three in Yehudah, as it says “Zenan, and Hadashah, and Migdal-gad.”
