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, ¹  to whom you have become unfaithful even though she is your companion and wife by law. ² 

Maleakhi 3:5

3:5 “I ³  will come to you in judgment. I will be quick to testify against those who practice divination, those who commit adultery, those who break promises, ⁴  and those who exploit workers, widows, and orphans, ⁵  who refuse to help ⁶  the immigrant ⁷  and in this way show they do not fear me,” says the Lord who rules over all.

[2:14]  ¹ tn Heb “the Lord is a witness between you and [between] the wife of your youth.”

[2:14]  ² 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.

[3:5]  ³ tn The first person pronoun (a reference to the Lord) indicates that the Lord himself now speaks (see also v. 1). The prophet speaks in vv. 2-4 (see also 2:17).

[3:5]  ⁴ tn Heb “those who swear [oaths] falsely.” Cf. NIV “perjurers”; TEV “those who give false testimony”; NLT “liars.”

[3:5]  ⁵ tn Heb “and against the oppressors of the worker for a wage, [the] widow and orphan.”

[3:5]  ⁶ tn Heb “those who turn aside.”

[3:5]  ⁷ tn Or “resident foreigner”; NIV “aliens”; NRSV “the alien.”
