Mishnayos Middos Perek 1 Mishnah 7

אחד פתוח לחיל – the opening that is in the north of the House of the Hearth was open to the Khel/the place within the fortification of the Temple, and the one in the south was open to the Temple courtyard.

פשפש קטן (a small wicket) – a small gate within the large gate [by which they entered to patrol].

שבו נכנסים לבלוש את העזרה (to patrol the Temple courtyard) – that they would enter each morning on the path of the same wicket to examine/search over each of the Temple vessels that were in the Temple courtyard that all of them were in their [appropriate] place. For this is taught in the Mishnah of Tractate Tamid [Chapter 1, Mishnah 3]: “He took the key and opened the wicket and entered from the House of the Hearth into the Temple courtyard, etc.,” – these walk on the covered place in front o the house in an easterly direction and those walk on the covered place in front of the house in a westerly direction. They would examine and go until they meet to the place where they make the cakes, they arrived, both sets say “Shalom; everything is peaceful/in order,” meaning to say, that all the Temple vessels are in their places in peace/in order.

לבלוש – it is the Aramaic translation of “and he searched,” and examined.
