Comentario sobre Menajot 13:3

לא יפחות משני זגירין – two large logs, for the least of wood is two.

[If one said,] “I take upon myself to bring [pieces of] wood,” he must bring not less than two logs. If one volunteers to bring wood to use on the altar, he must bring two logs. This is the amount of wood they put on the altar at one time.

והמעלה את הקומץ בחוץ חייב – [is liable for] extirpation, for it is an offering on the altar. But with this general rule it is also offering up a handful inside for the burning on the altar is valid; therefore, five handfuls are considered and not any more, for the person who offers up a handful inside is not considered as a sixth handful.

“Frankincense,” he must bring not less than a handful. If one volunteers to bring frankincense he must bring at least a handful of frankincense.

ושני בזיכים – of shewbread.

There are five cases of [not less than] a handful: One who says, “I take upon myself to bring frankincense,” he must bring not less than a handful. One who voluntarily offered a minhah must bring a handful of frankincense with it. One who offered up the handful outside [the Temp] is liable. The two dishes [of frankincense] require two handfuls. The mishnah now lists five cases where the minimum amount is a handful. The first is the case we just encountered in section two. The second case is one who volunteers to offer a minhah. He must bring with the minhah a handful of frankincense, the amount that always accompanies the minhah. The third case is who offers up a handful of incense outside of the Temple. Since a handful is an amount of significance within the Temple, one who offers up this amount outside of the Tempe is liable. The fourth and fifth handfuls are those that accompany the showbread (see above 11:5). Each row of the showbread had a dish of frankincense into which was put a handful of frankincense.
