פירוש על מדות 1:4

שער הדלק (the Gate of Kindling) – because they would bring in through there the wood for the pile of the wood on the altar was brought in that burn on the altar, it is called, the Gate of Kindling.

There were seven gates in the courtyard: three in the north and three in the south and one in the east.
In the south: the Gate of Kindling, and next to it the Gate of the First-borns, and then the Water Gate.
In the east: the Gate of Nicanor. It had two chambers, one on its right and one on its left. One was the chamber of Pinchas the dresser and one the other the chamber of the griddle cake makers.
Today’s mishnah lists the seven gates in the Temple courtyard.
Section two: The Gate of Kindling was used to bring in the wood for the altar.
Through the Gate of the First-borns they would bring in first-born animals on their way to being slaughtered. The Water Gate was used to bring in the water used on Sukkot for the water libation (it’s the most famous gate in history, but for other reasons).
Section three: Mishnah Yoma 3:10, mentions Nicanor and the doors for his gate, which according to legend were brought miraculously from Egypt. This gate was on the eastern side of the courtyard. Within the gate itself there were two chambers. In one sat Pinchas who made the priestly clothing (see Shekalim 5:1) and in the other sat the priests who made the griddle cakes that the high priest would offer every day (see Tamid 1:3).

שני לו שער הבכורות – we have the read, for there they wold bring in the firstlings whose slaughtering took place in the south.

שער המים – in the book of Ezekiel (47:1-2): “[He led me back to the entrance of the Temple, and I found that water was issuing from below the platform of the Temple – eastward, since the Temple faced east – but the water was running out at the south of the altar (i.e., southeast), under the south wall of the Temple. Then he led me out by way of the northern gate and led me around to the outside of the outer gate that faces in the direction of the east;] And I found that water was gushing from [under] the south wall,” and that is the south, which is called, “right” as it is written “north and eastward” (Psalm 89:13). And see Ezekiel in the prophecy that the waters went out from the House of the Holy of Holies thinly like the proboscides of locusts and when they reach this game, they become like the fulness of the mouth of a small jug, and that is why they call them מים מהכפכים/waters gushing (see Ezekiel 47:2- “[Then he led me out by way of the northern gate and led me around to the outside of the outer gate that faces in the direction of the east;] and I found that water was gushing from [under] the south wall.”).

שער ניקנור which is explained in Tractate Yoma (38a and Chapter 3, Mishnah 10- concerning the miracles of Nicanor with regard to the doors – see the Bartenura commentary there).

פנחס המלביש – who was appointed to dress the Kohanim at the time of their [Divine] Service, and to strip them of their clothing after the [Divine] Service and to guard the clothing of the priests.

לשכת עושי חביתין – in there they would make the meal-offering that the Kohen Gadol would offer on each day, “half of it in the morning and half of it in the evening” (Leviticus 6:13; see Tractate Tamid, Chapter 1, Mishnah 3),t and because it is stated regarding it (Leviticus 6:14): “shall be prepared with oil on a griddle,” it is called, a sort of cake.
