(1.) To speak intelligently, and as one that had acquaintance with God, v. 9. He having now a vision of the divine glory, the Lord put forth his hand, and by a sensible sign conferred upon him so much of the gift of the tongue as was necessary for him: He touched his mouth, and with that touch opened his lips, that his mouth should show forth God's praise, with that touch sweetly conveyed his words into his mouth, to be ready to him upon all occasions, so that he could never want words who was thus furnished by him that made man's mouth. God not only put knowledge into his head, but words into his mouth; for there are words which the Holy Ghost teaches, 1 Cor. ii. 13. It is fit God's message should be delivered in his own words, that it may be delivered accurately. Ezek. iii. 4, Speak with my words. And those that faithfully do so shall not want instructions as the case requires; God will give them a mouth and wisdom in that same hour, Matt. x. 19.
