'Skilled' in the Bible

The Lord answered, "This will happen because my people are foolish. They do not know me. They are like children who have no sense. They have no understanding. They are skilled at doing evil. They do not know how to do good."

The Lord who rules over all told me to say to this people, "Take note of what I say. Call for the women who mourn for the dead! Summon those who are the most skilled at it!"

For I will rouse into action and bring against Babylon a host of mighty nations from the land of the north. They will set up their battle lines against her. They will come from the north and capture her. Their arrows will be like a skilled soldier who does not return from the battle empty-handed.
