In the third aliyah of Parshas Balak, Bilaam's donkey speaks to him when he sees the angel blocking their path. There are many elements of the story relating to sight and speech, especially when viewed in contrast to Moshe Rabbeinu. Bilaam tries to use his power of speech to curse, and is not able to see the spirituality in front of him. On the other hand, Moshe's ability to speak comes from his spiritual encounters with Hashem, elevating these faculties to function in relation to divine matters. We strive to use our ability of sight and speech to further spiritual goals, as opposed to Bilaam, who attempted to do the opposite.
