The crowd was composed of Jews, not Gentiles (Acts 2:5). Joel's prophecy of the giving of the gifts was primarily concerning the Jews. Thus Peter makes the point to them: "The promise is unto you, and to your children" (Acts 2:39), perhaps referring to Joel's prophecy that the spirit would be given to the Jews and to their children (Acts 2:17 cp. Joel 2:28-32).
Mkutano ulikuwa ni wa Wayahudi, si watu wa Mataifa (Mdo. 2:5).Unabii wa Yoeli kupewa karama ulihusika hapo kwanza na Wayahudi pekee. Basi, Petro ana maana hii kwao: "Ahadi hii ni kwa ajili yenu, na kwa watoto wenu" (Mdo. 2:39), labda ilikuwa yataja unabii wa Yoeli ya kwamba Wayahudi watapewa Roho na watoto wao (Mdo. 2:17 linganisha Yoeli 2: 28 -32).
