That I speak, Heb. that I will speak. Shall I send, or who dare carry, a challenge from me to God, or a message that I am ready and desirous to debate with him concerning his proceedings? This indeed thou hast done in effect, but far be such presumption from me. If a man speak; if a man should be so bold and venturous to enter the lists with God. He shall be swallowed up with the sense of God's infinite majesty and spotless purity.
