'Art' in the Bible

The king answered and said to Daniel, whose name was Belteshazzar, Art thou able to make known unto me the dream which I have seen, and the interpretation thereof?

Thou, O king, art king of kings, unto whom the God of heaven hath given the kingdom, the power, and the strength, and the glory;

and wheresoever the children of men dwell, the beasts of the field and the birds of the heavens hath he given into thy hand, and hath made thee to rule over them all: thou art the head of gold.

This dream I, king Nebuchadnezzar, have seen; and thou, O Belteshazzar, declare the interpretation, forasmuch as all the wise men of my kingdom are not able to make known unto me the interpretation; but thou art able; for the spirit of the holy gods is in thee.

it is thou, O king, that art grown and become strong; for thy greatness is grown, and reacheth unto heaven, and thy dominion to the end of the earth.

Then was Daniel brought in before the king. The king spake and said unto Daniel, Art thou that Daniel, who art of the children of the captivity of Judah, whom the king my father brought out of Judah?

TEKEL; thou art weighed in the balances, and art found wanting.

At the beginning of thy supplications the commandment went forth, and I am come to tell thee; for thou art greatly beloved: therefore consider the matter, and understand the vision.
