Zechariah 4:5

Then; when the prophet had inquired into the meaning of these emblems. The angel that talked with me: see Malachi 1:19. Knowest thou not? it is not a question either to upbraid the prophet as an ignoramus, Christ doth not reproach his for not knowing deep and dark mysteries at first sight of them; nor is it the question of one that was uncertain about the thing inquired into, Christ knew the prophet's ignorance though he ask the question; but it is to excite him to attend and learn. And I said, No; Zechariah freely confesseth he knew not, he pretends not to know what indeed he did not know. My lord: he owns the greatness and sovereignty of Christ.
