SENAAH (sē-nā'a, Heb. senā’âh). The descendants of Senaah (sometimes called Hassenaah, with the Hebrew definite article attached). These people were a part of the company returning from captivity under Zerubbabel (Ezra.2.35; Neh.7.38). They rebuilt the Fish Gate of Jerusalem (Neh.3.3). The name may also refer to a place (unknown).

SENAAH sĭ nā’ ə (סְנָאָ֔ה; Apoc. Σαναάς). A clan or family who were among the returning exiles from Babylonia with Zerubbabel (Ezra 2:35; Neh 7:38; 1 Esd 5:23 KJV ANNAAS, ASV SANAAS), and helped rebuild the walls of Jerusalem (Neh 3:3). It is possible that they are the same as “Hassenuah,” a clan of Benjamin (1 Chron 9:7; Neh 11:9), and if so, the latter would be the correct reading.

International Standard Bible Encyclopedia (1915)

se-na’-a, sen’-a-a (cena’ah; Codex Vaticanus Sanana; Sananat; Codex Alexandrinus Sanana, Sennaa, Hasan): The children of Senaah are mentioned as having formed part of the company returning from the captivity with Zerubbabel (Ezr 2:35; Ne 7:38). The numbers vary as given by Ezr (3,630) and Ne (3,930), while 1 Esdras 5:23 puts them at 3,330. In the last place the name is Sanaas, the King James Version "Annaas" (Codex Vaticanus Sama; Codex Alexandrinus Sanaas). In Ne 3:3 the name occurs with the definite article, ha-senaah. The people may be identical with the Benjamite clan Hassenuah (1Ch 9:7). Eusebius, in Onomasticon, speaks of Magdalsenna a village about 7 miles North of Jericho, which may be the place intended; but the site is not known.
