Maleakhi 2:2

2:2 If you do not listen and take seriously ¹  the need to honor my name,” says the Lord who rules over all, “I will send judgment ²  on you and turn your blessings into curses – indeed, I have already done so because you are not taking it to heart.

Maleakhi 2:14

2:14 Yet you ask, “Why?” The Lord is testifying against you on behalf of the wife you married when you were young, ³  to whom you have become unfaithful even though she is your companion and wife by law. ⁴ 

[2:2]  ¹ tn Heb “and if you do not place upon [the] heart”; KJV, NAB, NRSV “lay it to heart.”

[2:2]  ² tn Heb “the curse” (so NASB, NRSV); NLT “a terrible curse.”

[2:14]  ³ tn Heb “the Lord is a witness between you and [between] the wife of your youth.”

[2:14]  ⁴ sn Though there is no explicit reference to marriage vows in the OT (but see Job 7:13; Prov 2:17; Ezek 16:8), the term law (Heb “covenant”) here asserts that such vows or agreements must have existed. References to divorce documents (e.g., Deut 24:1-3; Jer 3:8) also presuppose the existence of marriage documents.
