'Art' in the Bible

Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, Surely a bridegroom of blood art thou to me.

So he let him alone. Then she said, A bridegroom of blood art thou , because of the circumcision.

Thou wilt surely wear away, both thou, and this people that is with thee: for the thing is too heavy for thee; thou art not able to perform it thyself alone.

And thou shalt make it a holy anointing oil, a perfume compounded after the art of the perfumer: it shall be a holy anointing oil.

and thou shalt make of it incense, a perfume after the art of the perfumer, seasoned with salt, pure and holy:

unto a land flowing with milk and honey: for I will not go up in the midst of thee, for thou art a stiffnecked people, lest I consume thee in the way.

And he said, Behold, I make a covenant: before all thy people I will do marvels, such as have not been wrought in all the earth, nor in any nation; and all the people among which thou art shall see the work of Jehovah; for it is a terrible thing that I do with thee.

And he made the holy anointing oil, and the pure incense of sweet spices, after the art of the perfumer.
