God gives a great blessing to the tribe of Levi.
“Bless all his skills, O Lord, and be pleased with the work of his hands.”

Isn’t this a blessing that every Christian should want? No matter what our skills are; manual labor, missionary work, office work, teaching, ministering, nursing, housework, heads of corporations, etc. shouldn’t we want all our skills to be blessed?
Col 3:23-24
Whatever you do, work at it with all your heart, as working for the Lord, not for men, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.

Scripture says that when Moses died “his eyes were not weak nor his strength gone.”
Sounds like he was still healthy and strong. It's just that his time was up. His eyes must have been pretty strong to be able to see all that land from the top of Mount Nebo! Moses was able to “see” from the tip of the Dead Sea (Zoar) to way north of the Sea of Galilee (Dan).
