laylah

The lexica are unanimous that לַיְלָה denotes night, the dark portion of the daily cycle and the standing counterpart of יוֹם. Totals differ by counting method: roughly 233 on the traditional lemma count, 235 in the Leningrad Codex across 223 verses, and higher again in BDB's reference tally once variants are folded in. Despite the final ־ָה the noun takes masculine agreement, and its plural לֵילוֹת is a mismatched form. BDB, following Nöldeke, Delitzsch and König, and GKC §90, treats that ending as radical, an original part of a reconstructed base *laylay, rather than the directional he, with the shorter לַיִל and לֵיל preserving the older shape; the functional argument is decisive, since the directional ending means motion toward and adverbial לַיְלָה means during. Cognates run across Semitic (Arabic layl, Aramaic and Syriac lelya, Akkadian lilatu "evening", Ugaritic), pointing to a base *layl. The Septuagint renders the word with νύξ and its compounds, including adverbial νυκτός and μεσονύκτιον.

Three discussions dominate the secondary literature. First, the theology of Genesis 1: von Rad, Westermann and Mark S. Smith read the naming and bounding of night as a deliberate critique of Near Eastern conflict cosmogony, while Levenson and Batto hold that the chaos motif is only partly domesticated, so night keeps a residual charge. Second, the cultural coding of night, both as the privileged time of the message dream and incubation (Oppenheim, Gnuse, Husser) and as the time of danger and possible demonic threat (Tate on Psalm 91:5; Malul's DDD article on the terror of the night; Barbiero on the apotropaic reading of Song of Songs 3:7-8), against the counter theme of nocturnal prayer, recitation and vigil (Psalm 1:2; 119:55, 62; 134:1; the Community Rule 1QS 6:6-8; Philo on the Therapeutae), with the night divided into three watches on the biblical and Babylonian scheme as against the later Roman four. Third, whether the Israelite day was reckoned from evening or from morning, which Stern, Ben-Dov, Milgrom, de Vaux and Talmon leave genuinely open.

A fourth debate touches the root only indirectly. לִילִית at Isaiah 34:14 was tied by Schrader, Levy, Sayce and Fossey to Akkadian lilitu and the lilu demons, and so to לַיְלָה. The competing Sumerian lil ("air, wind") derivation, Blair's de-demonizing reading of the Isaianic list as animals, and Lambert's and Farber's cautions about the Gilgamesh Tablet XII appendix and the Arslan Tash amulets have moved the mainstream toward treating the tie to "night" as folk etymology, a reading the Septuagint's ὀνοκένταυρος supports. The plural at Isaiah 34:14 in the Great Isaiah Scroll and the term's appearance among the monsters of 4Q510-511 nonetheless show that Second Temple readers could take it demonologically.
