מַה־דּוֹדֵ֣ךְ מִדּ֔וֹד הַיָּפָ֖ה בַּנָּשִׁ֑ים מַה־דּוֹדֵ֣ךְ מִדּ֔וֹד שֶׁכָּ֖כָה הִשְׁבַּעְתָּֽנוּ׃
Wie sieht dein Geliebter aus unter den anderen Jünglingen, du Schönste der Frauen? Was ist dein Geliebter unter andern Jünglingen, dass du uns also beschworen? —
Rashi
With what does your beloved excel another beloved. This is what the nations were asking Yisroel, “What is it about your God more than all the other gods, that you allow yourselves to be burned and hanged because of Him?”36I.e., why are you so loyal to a God Who has forsaken you? (Metzudas Dovid)
Ezra ben Solomon
How is your beloved fairer than another, From all of the seventy thrones of Kingship.
Rashi
That you bind us under oath. To testify before Him about your love.
