'Art' in the Bible

And each of the four living creatures had six wings, and in every direction, and within, are full of eyes; and day after day, and night after night, they never cease saying, "Holy, holy, holy, Lord God, the Ruler of all, who wast and art and evermore shalt be."

saying, "We give thee thanks, O Lord God, the Ruler of all, Who art and wast, because Thou hast exerted Thy power, Thy great power, and hast become King.

Who shall not be afraid, O Lord, and glorify Thy name? For Thou alone art holy. All nations shall come and shall worship Thee, because the righteousness of all that Thou hast done has been made manifest."

And I heard the angel of the waters say, "Righteous art Thou, who art and wast, the holy One, because Thou hast thus taken vengeance.
