Or HaChaim on Numbers 14:22/אור החיים על במדבר י״ד:כ״ב

1 ולא שמעו בקולי, "and who did not listen to My voice." Inasmuch as the Jewish people had previously been granted the privilege to be personally addressed by G'd at Mount Sinai, G'd now was very angry that they had not listened to His voice at this time.
