אֵ֚לֶּה קריאי [קְרוּאֵ֣י] הָעֵדָ֔ה נְשִׂיאֵ֖י מַטּ֣וֹת אֲבוֹתָ֑ם רָאשֵׁ֛י אַלְפֵ֥י יִשְׂרָאֵ֖ל הֵֽם׃
그들은 회중에서 부름을 받은 자요 그 조상 지파의 족장으로서 이스라엘 천만 인의 두령이라
Rashi on Numbers
אלה קרואי העדה THESE WERE THOSE CALLED OF THE CONGREGATION — those who were called upon for every matter of importance that happened in the congregation.
Tur HaArokh
קרואי העדה, “the above named were so described as their importance was such that no decisions were taken unless these men were present.”
Siftei Chakhamim
To everything of importance. Rashi wishes to explain: Was their importance [only] that they called to the entire the congregation? Thus Rashi explains they were “invited to everything” meaning they were invited to deliberate and decide matters affecting the congregation.
