Reference for Menachot 26:2
להקטיר לבונתה למחר רבי יוסי אומר פסול ואין בו כרת: אמר ר"ל אומר היה ר' יוסי אין מתיר מפגל את המתיר
Resh Lakish said, R'Jose laid down the principle that a 'mattir cannot render piggul the other mattir.<span class="x" onmousemove="('comment',' R. Jose holds that in every offering in which there are two mattirs, a wrongful intention expressed during the service of one mattir with regard to the other mattir is of no consequence; thus an intention expressed during the burning of the handful (the first mattir) to burn the frankincense');"><sup>2</sup></span> So, too, you may say of the two dishes of frankincense of the Shewbread, that one mattir cannot render piggul the other mattir.<span class="x" onmousemove="('comment',' The two dishes of frankincense are the mattirs of the Shewbread, for only after the burning of both dishes are the twelve loaves of the Shewbread permitted to be eaten by the priests. Now if a wrongful Intention was expressed during the burning of the one dish in respect of the other dish (e.g., to burn the other dish on the morrow) , it is of no consequence.');"><sup>3</sup></span>
