Midrash su Salmi 4:8

What is written above this? “And the Lord said to Moses: Speak to your brother Aaron…” (Leviticus 16:2) R’ Avin said: He said to him - go and comfort him with words, as it says “Speak to the heart of Jerusalem…” (Isaiah 40:2) “…that he should not come at all times…” (Leviticus 16:2) R’ Yehudah bar R’ Simon said: Moshe was greatly distressed by this. He said: oy! Perhaps Aharon my brother has been driven out from the inner space at all times! There is a time corresponding to the hour “…that he should not come at all times…” (ibid.) There is a time corresponding to the day “And water by measure you shall drink…” (Ezekiel 4:11) There is a time corresponding to the year, as it says “And it was, at the return of the year…” (Samuel II 11:1) There is a time corresponding to twelve years “Until the time when His word came…” (Psalms 105:19) There is a time corresponding to the seventy years, as it says “…since the destruction of Jerusalem seventy years.” (Daniel 9:2) And it says “…until the time of his own land come…” (Jeremiah 27:7) There is a time corresponding to eternity “You gave joy into my heart from the time that their corn…” (Psalms 4:8) The Holy One said to Moshe: it is not as you think. This is not a time of the hour, the day, the year, of twelve years, seventy years or of eternity. Rather, at any time which he wants to enter he may enter, but he must do it with this procedure. R’ Yehudah bar R’ Elazar said: with thirty-six bells and thirty-six pomegranates. The Rabbis say: with seventy-two bells and seventy-two pomegranates.
