Genesis 46:30

אמותה הפעם NOW, I WILL FAIN DIE — It's literal meaning is as the Targum renders it. A Midrashic explanation is (being based upon the literal translation. “I will die this once”): I had thought that I would die two deaths, in this world and also in the world to come, because the Divine Presence departed from me and I therefore thought that God would hold me responsible for your death. Now, since you are alive I will die only once, in this world (Midrash Tanchuma, Vayigash 9).

וַיֹּ֧אמֶר יִשְׂרָאֵ֛ל אֶל־יוֹסֵ֖ף אָמ֣וּתָה הַפָּ֑עַם אַחֲרֵי֙ רְאוֹתִ֣י אֶת־פָּנֶ֔יךָ כִּ֥י עוֹדְךָ֖ חָֽי׃

And Yisra᾽el said to Yosef, Now let me die, since I have seen thy face, because thou art still alive.
