rumour--of the advance of the foe, and of his cruelty (Mt 24:6).

seek a vision--to find some way of escape from their difficulties (Is 26:9). So Zedekiah consulted Jeremiah (Jr 37:17; 38:14).

law shall perish--fulfilled (Eze 20:1, 3; Psa 74:9; La 2:9; compare Am 8:11); God will thus set aside the idle boast, "The law shall not perish from the priest" (Jr 18:18).

ancients--the ecclesiastical rulers of the people.
