(Heb. Rejy', רֵעַי , friendly; Sept. ῾Ρηϊ v v. r. ῾Ρησί ), one of king David's officers, who refused to rebel with Adonijah (1 Kings 1:8). B.C. 1015. "Jerome (Qucest. Hebr. ad loc.) states that he is the same with ‘ Hiram the Zairite,' i.e. Ira the Jairite, a priest or prince about the person of David. Ewald (Gesch. 3:266, note), dwelling on the occurrence of Shimei in the same list with Rei, suggests that the two are David's only surviving brothers, Rei being identical with RADDAI. This is ingenious, but there is nothing to support it, while there is the great objection to it that the names are in the original extremely dissimilar, Rei containing the Ain, a letter which is rarely exchanged for any other, but apparently never for Daleth (Gesenius, Theaur. p. 976)"
