Charles Ellicott Commentary Hosea 2:19-20

"And I will betroth thee unto me for ever; yea, I will betroth thee unto me in righteousness, and in justice, and in lovingkindness, and in mercies. I will even betroth thee unto me in faithfulness; and thou shalt know Jehovah." — Hosea 2:19-20 (ASV)

Then Jehovah, turning again to the wife of His youth, says to her, “I will betroth thee” (as at the first, when an undefiled young woman). Three times is this phrase repeated. “Righteousness” and “judgment” indicate the equitable terms on which God would accept the penitent; and so that this thought would not crush her with fear, “lovingkindness” and “tender mercies” follow. And so that this would not seem too good, He adds “with faithfulness” (to Myself).

I will betroth thee.— It is in the betrothal of humanity to God in Christ’s incarnation that the human race, which had so deeply revolted, returns to Him, and knows the Lord.
