And I have filled him with the spirit of God, in wisdom, and in understanding, and in knowledge, and in all manner of workmanship, I have filled him with the spirit of God - See Clarke's note on Exodus 28:3.
In wisdom - חכמה, chochmah, from חכם chacham, to be wise, skillful, or prudent, denoting the compass of mind and strength of capacity necessary to form a wise man: hence our word wisdom, the power of judging what is wise or best to be done; from the Saxon, to teach, to advise, and to judge; hence the doom or judgment of the well taught, wise, or prudent man.
Understanding - תבונה tebunah, from בן ban or bun, to separate, distinguish, discern; capacity to comprehend the different parts of a work, how to connect, arrange, etc., in order to make a complete whole.
Knowledge - דעת daath, denoting particular acquaintance with a person or thing; practical, experimental knowledge.
