I will betroth you: This Hebrew verb, used three times in these verses, can be translated with the word betroth. In ancient times, betrothal included all the legal steps of marriage, like the groom paying a bride price. The only things missing were the marriage ceremony and sexual consummation. The Lord promised to betroth Israel to himself forever.
To ensure this eternal marriage, God provided a bride price with five priceless qualities:
Righteousness
Justice
Unfailing love
Compassion
Faithfulness
As a result, the Lord said, Israel will finally know me (compare Hosea 2:13).
