In my text it is verse 21. God is speaking to the children of Israel (represented by the woman -- the "virgin of Israel in the previous verse) telling her/it that they need to return to their place and not hide from God. God has created a new system in which the female is allowed to pursue the male (the nation can appeal to God instead of waiting for the male/God to approach them).
The classic commentator, Rabbi Shlomo Yitzchaki wrote "will you hide: will you hide from Me, that you are ashamed to return to Me because of your way? Behold, something new has been created on earth, that a woman shall go after a man to seek him that he should marry her. This is an expression of “and I will go around (וַאֲסוֹבְבָה) in the city; I will seek, etc.” (Song 3:2). " He also speaks of another interpretation in which the feminine persona of Israel will become a mae persona -- instead of inheriting a percentage as a daughter, the nation will inherit everything as a son:
"And in the name of Rabbi Judah the Preacher I heard: A woman shall turn around to become a man. I gave you like a daughter, who receives a tenth of the property of her father, seven nations out of seventy. Ultimately, you shall take everything like a son, a male, who inherits everything."
