'Art' in the Bible

O thou that art named the house of Jacob, is the spirit of the LORD straitened? are these his doings? do not my words do good to him that walketh uprightly?

Be pained, and bring forth, O daughter of Zion, As a travailing woman, For now, thou goest forth from the city, And thou hast dwelt in the field, And thou hast gone unto Babylon, There thou art delivered, There redeem thee doth Jehovah from the hand of thine enemies.

But thou, Beth-lehem Ephrathah, which art little to be among the thousands of Judah, out of thee shall one come forth unto me that is to be ruler in Israel; whose goings forth are from of old, from everlasting.

Thou -- thou eatest, and thou art not satisfied, And thy pit is in thy midst, And thou removest, and dost not deliver, And that which thou deliverest, to a sword I give.
