'Merchant' in the Bible

And Abraham hearkened to Ephron; and Abraham weighed to Ephron the money that he had named in the ears of the sons of Heth four hundred shekels of silver, current with the merchant.

She maketh body linen and selleth it, and delivereth girdles unto the merchant.

Who is this, she that cometh up from the wilderness Like pillars of smoke, Perfumed with myrrh and frankincense, With all powders of the merchant? ...

He is a merchant, balances of deceit are in his hand; he loveth to oppress.
