Job 12:8-11

The earth cannot talk to you, but you can ask questions of the earth, by your mind looking at it and asking, "Why is that thing the way it is? I think I'll study that and see why that is the way it is." And so you study aspects of the creation, whether in botany, biology, geology, archaeology, you name it. It brings us a measure of learning about God by observing the things that He has made.

What is the context? The "words" are the instruction that come from God's creation. The words are actually in your own mind, but they are formulated by the thought you are having about what you are observing in God's creation. "Doesn't the ear test words?" You turn it over in your mind and you reach conclusions about it.

What Job is saying is that there is deliberate instruction from the Creator in the world around us so that we are without excuse if we say we have no models or examples about things. It is saying that God intends that we use the senses to observe what He has made and derive wisdom from it.
