2. He must give notice of what he heard. As a watchman must have eyes in his head, so he must have a tongue in his head; if he be dumb, it is as bad as if he were blind, Isa. lvi. 10. Thou shalt give them warning from me, sound an alarm in the holy mountain; not in his own name, or as from himself, but in God's name, and from him. Ministers are God's mouth to the children of men. The scriptures are written for our admonition. By them is thy servant warned, Ps. xix. 11. But, because that which is delivered vivâ voce—by the living voice, commonly makes the deepest impression, God is pleased, by men like ourselves, who are equally concerned, to enforce upon us the warnings of the written word. Now the prophet, in his preaching, must distinguish between the wicked and the righteous, the precious and the vile, and in his applications must suit his alarms to each, giving every one his portion; and, if he did this, he should have the comfort of it, whatever the success was, but, if not, he was accountable.
