'Skilled' in the Bible

“For My people are fools;they do not know Me.They are foolish children,without understanding.They are skilled in doing what is evil,but they do not know how to do what is good.”

Beaten silver is brought from Tarshish,and gold from Uphazfrom the hands of a goldsmith,the work of a craftsman.Their clothing is blue and purple,all the work of skilled artisans.

For I will soon stir up and bring against Babylonan assembly of great nations from the north country.They will line up in battle formation against her;from there she will be captured.Their arrows will be like those of a skilled warriorwho does not return empty-handed.
