yes these three things work together, wisdom knowledge and understanding. and they can never be differentiated or separated.

but having knowledge alone is not enough to live, and also having understanding of what you know is not enough, but ultimately adding wisdom by applying what you know and understand is the greatest.

but you can never be wise or called a wise person without first acquiring knowledge and understanding.

and the Bible says wisdom is the principal thing so get wisdom and in all thy getting get understanding, so these two things are the most priority but for knowledge you acquire it day by day.
