sal'-a-i, sal'-i (callay; Salom; Codex Alexandrinus Salo, with variants):
(1) Eponym of a Benjamite family which settled at Jerusalem after the return, descendants of "Sallu" (1 Chronicles 9:7 Nehemiah 11:7, 8); the pedigrees of Sallu differ decidedly in the two passages. Curtis (ICC) suggests that "son of Hodaviah, the son of Hassenuah" (Chronicles) is a corruption or derivation of "Judah the son of Hassenuah" (Nehemiah).
(2) Name of a priestly family (Nehemiah 12:20), called "Sallu" in Nehemiah 12:7.
