'Expert' in the Bible

The priests did not say, Where is the Lord? and those who were expert in the law had no knowledge of me: and the rulers did evil against me, and the prophets became prophets of the Baal, going after things without value.

Is there no life-giving oil in Gilead? is there no expert in medical arts? why then have my people not been made well?

Silver hammered into plates is sent from Tarshish, and gold from Uphaz, the work of the expert workman and of the hands of the gold-worker; blue and purple is their clothing, all the work of expert men.

The Lord gave me a vision, and I saw two baskets full of figs put in front of the Temple of the Lord, after Nebuchadrezzar, king of Babylon, had taken prisoner Jeconiah, the son of Jehoiakim, king of Judah, and the chiefs of Judah, and the expert workmen and metal-workers from Jerusalem, and had taken them to Babylon.

(After Jeconiah the king and the queen-mother and the unsexed servants and the rulers of Judah and Jerusalem and the expert workmen and the metal-workers had gone away from Jerusalem;)

For see, I am moving and sending up against Babylon a band of great nations from the north country: and they will put their armies in position against her; and from there she will be taken: their arrows will be like those of an expert man of war; not one will come back without getting its mark.
