Psalm 1/Notes/Lexical.v. 1.112240
v. 1. Despite its appearance in most translations, the phrase happy is the one (אַשְׁרֵי־הָאִישׁ) is not a complete sentence; it is a Hebrew construct chain] (lit.: "the happiness of the one" = "the happiness experienced by the one;" cf. NLT: "Oh, the joys of those..."). As a sentence fragment, it functions not as an assertion, but as an exclamation which expresses "an attitude of admiration"' (SDBH) and a "desirous longing of one person for the condition of another" (Janzen, 1965, 215-226). English has no equivalent expression, though it is similar to the exclamation "congratulations!" (cf. TWOT) or to the words spoken in a celebratory toast to some person: "Here's to the one!" The word "happy" has been translated variously as "blessed" (KJV, NIV, ESV, NASB; cf. Jerome beatus and LXX μακάριος), "happy" (NRSV, GNT, CSB, JPS 1917), "joys" (NLT) etc. The meaning of the word per se is less important than the function of the phrase to express admiration and celebration. First Kings 10:8 offers a helpful illustration of the phrase in use. When the Queen of Sheba saw the wealth and Wisdom and King Solomon, she exclaimed, “Happy are your men! Happy are these servants of yours, who continually stand before you and listen to your wisdom!” (1 Kings 10:8). Even though the Queen was a figure of royalty with all the privilege which that entails, she looked up to Solomon’s servants with admiration, because they had the privilege of continually hearing Solomon’s wisdom. She considered their position to be desirable, and so she called them "happy."
Interpreters differ as to whether "the one" (הָאִישׁ) is a unique individual (i.e. a king) or a literary representative of a group (i.e. a typical righteous person). The latter interpretation is reflected in those translations that translate הָאִישׁ with a plural and gender-neutral term (e.g., CEV, ERV, GNB, NLT). Other translations use a gender-neutral term but retain the singular referent (e.g. CSB, NET, NIV, LPDPT). Older translations tend to use masculine singular terms (LXX, Tg, Jer, KJV, Reina Valera, ESV, NVI, LS 1910). In either case, the tree imagery of v. 3, the allusion to Deuteronomy's kingship law (Deut 17) in v. 2, and the linguistic/thematic connections between Psalm 1 and Psalm 2 all work together to give "the one" "a distinctly royal profile" (Brown 2002). Although it is possible to explain this royal profile in terms of democratization - the office of king is democratized so that everyone who follows the path of Torah is a kind of king (so e.g., Brown 2002; Barbiero 2003), others have argued on the basis of the Joshua-like description of "the one" (cf. Schnittjer 2021, 471; Mitchell 2016), the connections between "the one" of Psalm 1 and the anointed king of Ps 2, and the Messianic shape of the Psalter, that "the one" is a unique royal figure.
