וְאֵרַשְׂתִּ֥יךְ לִ֖י בֶּאֱמוּנָ֑ה וְיָדַ֖עַתְּ אֶת־יְהוָֽה׃ (ס)
진실함으로 네게 장가들리니 네가 여호와를 알리라
Tze'enah Ure'enah
“And I will espouse you with faithfulness and you will be devoted to the Lord” [2:22]. I will betroth you because of the merit that you will believe in Me with truth.
Rashi
And I will betroth you to Me with faith For the reward of the faith, for, while in exile, you believed in the promises through My prophets. [from Mechilta 14:31 with variations]
