'Skilful' in the Bible

Then I saw all labor and every skilful work, that for this a man is envied of his neighbor. This also is vanity and a striving after wind.

I have turned so as to see under the sun, that not to the swift is the race, nor to the mighty the battle, nor even to the wise bread, nor even to the intelligent wealth, nor even to the skilful grace, for time and chance happen with them all.
