kri'-er (qara'; compare boao):
(1) Neither is this exact word found in English Versions of the Bible, nor a word exactly corresponding to it in the Hebrew Bible, but the character it stands for appears as "one who cries aloud," i.e., proclaims mandates or gives public messages. In Proverbs 1:21 it is said, "She (Wisdom) crieth in the chief place of concourse." John the Baptist calls himself "the voice of one crying in the wilderness" (John 1:23)-like a herald going before the king.
(2) In the East today every village even has its public crier, selected for his loud or penetrating voice, and appointed to give notice of the fresh orders or mandates of the mudir ("governor") or other authorities. The muezzin of the Moslems, who at the five appointed times of prayer mounts the minaret and calls the faithful to prayer, is another striking example. Something like the ancient "heralds" of the king were the "heralds" of the Middle Ages in Europe who, preceded by trumpeters, made official proclamations:
