Possible interpretations: 1) The woman contrasts the way she wants to give herself to the man, who will give her his love, to the way Solomon leases out his vineyard to those who will give him money. 2) The man contrasts the woman, whom he will not give to another man, to Solomon's vineyard, which he gave to other men.
It may be helpful to state that this payment was for the fruit of the vineyard. Alternate translation: "Each man was supposed to give Solomon a thousand shekels as payment for the fruit of the vineyard" (See: [[rc://en/ta/man/jit/figs-explicit]])
Some versions understand the woman to be speaking directly to Solomon. Others understand her to be speaking in an apostrophe to her friends, to the man, or to herself. (See: [[rc://en/ta/man/jit/figs-apostrophe]])
