'Tongue' in the Bible

And Moses said unto Jehovah, Oh, Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant; for I am slow of speech, and of a slow tongue.

But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that Jehovah doth make a distinction between the Egyptians and Israel.
