This shows us that Laban was as great as Bilaam. He asks, Why is it written, "that you speak not," rather than 'that you harm not?' He answers, Laban did not chase Jacob with an army of men to wage war against him, for the power of Jacob and his sons is greater than that of Laban. But he chased him to kill him with his mouth and destroy everything, as it is written, "An Aramian wanted to destroy my father." This is why it says, "that you speak not," and not, 'that you harm not'. It is also written, "It is in the power of my hand to do." How did he know he had the power?
