'Skillfulness' in the Bible

So David shepherded them according to the integrity of his heart;And guided them with his skillful hands.

For there is a man whose labor is with wisdom, with knowledge, and with skillfulness; yet he shall leave it for his portion to a man who has not labored for it. This also is vanity and a great evil.

And Moab will spread out his hands in the middle of the filthAs a swimmer spreads out his hands to swim,But the Lord will humiliate his pride in spite of the [skillful] movements of his hands.
