Talmud su Salmi 141:2

There (Pesaḥim 5:1) we have stated: “The perpetual sacrifice is slaughtered at 8:30 hours⁴⁵The count starts at sunrise. At the equinox, 8:30 in the day is 2:30 pm (14:30). and brought at 9:30 hours. On Passover Eve days⁴⁶The afternoons of the 14th of Nisan and of the 14th of Iyar. it is sacrificed at 7:30 hours and brought at 8:30 hours, whether it be weekday or Sabbath.” Rebbi Jeremiah asked: Here⁴⁷Regarding prayer, the Mishnah states that Minḥah is 2½ hours before night. The next “here” refers to the evening sacrifice which on ordinary days is slaughtered at 8:30 hours, 3½ hours before sundown. If the rules of prayer are derived from the rules of sacrifice then the time of Minḥah prayers should be fixed at 3½ hours before sundown! you make Minḥah at two and a half hours and here you make Minḥah at three and a half hours? Rebbi Yose said, Minḥah prayer was not bound to the perpetual sacrifice of evening but to incense burning⁴⁸The evening portion of incense was burned at the time of lighting the candelabra, after all sacrifices had been offered (Ex. 30:8).. What is the reason? (Ps. 141:2): “May my prayer be prepared as incense before You, the lifting up of my hands as the gift of evening.” Take one hour for its⁴⁹The perpetual sacrifice’s. preparation and you make Minḥah at two and one half hours.
