Proverbs 31 is the 31st and final chapter of the Book of Proverbs in the Hebrew Bible or the Old Testament of the Christian Bible.^[1] Verses 1 to 9 present the advice which King Lemuel's mother gave to him, about how a just king should reign. The remaining verses detail the attributes of a good wife or an ideal woman (verses 10–31). The latter section is also known as Eshet Ḥayil.^[2]

In this part, an unnamed queen-mother gives instruction to her son, King Lemuel, on his duty to administer justice.^[2] Using the appeal to his filial respect to a mother and his birth as an answer of a prayer (verse 2, cf. 1 Samuel 1:11), the mother warns the king against sexual promiscuity and drunkenness (verses 3–7).^[2] The eighth and ninth verses are an appeal against inequality and injustice.^[7][8]

Verses 10–31 of this chapter, also called Eshet Ḥayil (אשת חיל, woman of valor), form a poem in praise of the good wife, a definition of a perfect wife or "ideal woman" in the nation of Israel, who is 'an industrious housewife, a shrewd businesswoman, an enterprising trader, a generous benefactor (verse 20) and a wise teacher (verse 26).^[2] This "Woman of Valor" has been described as the personification of wisdom, or in some sense as a description of a particular class of women in Israel, Persia, or in Hellenistic society.^[9] Some^[who?] see this as a praise directed from the husband to his wife.

It is one of the thirteen alphabetical acrostic poems in the Bible, where each line begins with a successive letter in the Hebrew alphabet.^[2] The word חיל (Ḥayil) appears in verses 10 and 29 of the passage, thought as the summary of the good woman's character. Traditionally it has been translated as "virtuous" or "noble". Some scholars have suggested that it rather means "forceful", "mighty", or "valiant", because this word is almost exclusively used in the Tanakh with reference to warfare.^[10]

Aberdeen theologian Kenneth Aitken notes that in view of the warnings against women portrayed as dangerous or adulterous in chapters 1 to 9, it is "fitting" that the book ends by "directing the attention of prospective bridegrooms to the ideal wife".^[2]

This chapter is recited on Friday night before Shabbat dinner in some Jewish homes.

The chapter has been emphasized within the biblical womanhood movement, and a number of books have been published on the "Proverbs 31 woman".^{[12][13][14][15][16]} This emphasis has been subject to criticism in Christian articles.^[17][18]
