Kindling the Lamps and Burning the Morning Incense

"In the morning, in the morning, when he tends them" (Exodus 30:7). We learned in a mishnah: he shall not tend the lamps and afterward burn the incense; rather he shall burn the incense and afterward tend the lamps. Abba Shaul says: he tends them and afterward burns the incense. What is Abba Shaul's reasoning? Because it is written "in the morning, in the morning, when he tends the lamps," and afterward "he shall burn it." And the Sages — what is the Merciful One saying? That at the time of tending he shall be burning the incense. For if you do not say so, then concerning the afternoon, where it is written "and when Aaron lights the lamps toward evening he shall burn it" (Exodus 30:8), would you likewise say that there too he first kindles the lamps and then burns the afternoon incense? And if you would say yes indeed it is so — but was it not taught: "from evening until morning" (Exodus 27:21) means give the lamp its measure of oil so that it will burn steadily on from evening until morning,
