Lévitique 6:7

And this is the law of the Mincha, which the priests, the sons of Aharon, shall offer in the presence of the Lord before the altar.

This passage supplements what was written in the parasha of Vayyiqra [2:1]. to offer This word is in the infinitive form, and here means shall offer the sons of Aaron any one of them, hence Scripture uses the singular he will scoop up.

AND THIS IS THE LAW OF THE MEAL-OFFERING. This section, according to the plain meaning of Scripture, adds [to Chapter 2 above where the law of the meal-offering was discussed] four commandments about the meal-offering: that [the residue be] eaten unleavened, that it be eaten in the Court of the Tent of Meeting, that every male among the children of Aaron may eat of it, and that whatever touches it becomes holy.
Now according to the Rabbinical interpretation thereof, there are many new teachings added [in this section, among them being the following]: that even of a meal-offering brought by priests the handful is taken out [and burnt on the altar, in the same way as the residue which must be burnt on the altar]; burnt (further, Verse 16). The question appears: is it necessary that a handful thereof be taken by a priest and be burnt separately on the altar, or that the whole meal-offering should be burnt at the same time as a unit? According to the text in Ramban before us, the answer is clearly in the affirmative. Scholars, however, have pointed to the Talmud (in Menachoth 72 b) where the conclusion is contrary to this text. The suggestion has therefore been made that the text here is faulty, and should be emended to read: “that even a meal-offering of priests requires ‘oil and frankincense’” (mentioned in Verse 8). See my Hebrew commentary, p. 29. that the priest must bring it near before the Eternal which means to the western corner [of the altar, since the Tent of Meeting where the ark of the covenant stood, was to the west of the altar, and therefore nearest to it], and in front of the altar which means to the southern corner [since the ramp of the altar which is its “front,” was on the south side thereof]. Thus you find that it had to be “presented” [i.e., brought near] to the southwestern corner of the altar. [And this section further teaches:] And he shall take up from it a handful — “from it” as one joined mass, meaning that he is not to bring one tenth of an ephah of flour [which is the amount brought for a meal-offering] in two receptacles [but it must be a full tenth of an ephah in one receptacle], nor is he to make a fixed measure that holds as much as his handful [to remove the amount of flour for the altar, but he must do it with his hand]. He also states, It shall not be baked as anything leavened. This is to liken all the stages of work [in the preparation of the meal-offering] to baking, thus teaching that one is also liable for kneading and rolling it if it be leavened, and that for each and every such act he transgresses a negative commandment and is liable to whipping on each count.

לפני המזבח, now the Torah explains the “Torah” of the gift-offering, מנחה, explaining that all of it is to be brought לפני המזבח “in front of the altar” as opposed to the Olah which was brought on the מוקד of the altar. All sacrifices are brought directly and exclusively to G’d. The parts allocated to the priests are not allocated by the owners of the sacrifice, but are to be viewed as G’d inviting the priests to be guests at His table, in Talmudic parlance as משלחן גבוה קא זכו, “they are benefiting from a table in the celestial regions.” The gift offering by a priest ends up on the altar completely as opposed to that of ordinary Israelites’ gift offering of which only a fistful gets to the altar, the balance being eaten by the priests.
