Charles Ellicott Commentary Exodus 31:3-4

"and I have filled him with the Spirit of God, in wisdom, and in understanding, and in knowledge, and in all manner of workmanship, to devise skilful works, to work in gold, and in silver, and in brass," — Exodus 31:3-4 (ASV)

I have filled him with the spirit of God ... to devise cunning works. —Every good gift and every perfect gift (intellectual power no less than others) is from above, and comes down from the Father of lights (James 1:17). Artistic ability is a Divine gift, a very precious gift, best employed in God’s direct service, and always to be employed in subordination to His will, as an improving, elevating, and refining—not as a corrupting—influence.

In wisdom, and in understanding, and in knowledge. —By “wisdom” is probably meant the power to invent and originate artistic forms; by “understanding,” the ability to appreciate artistic suggestions received from others; by “knowledge,” acquaintance with the methods and processes of art. Bezaleel was to possess all these gifts.

In all manner of workmanship. —He was also to possess that wonderful dexterity of hand on which the power of artistic execution mainly depends.
