Easton's Bible Dictionary (1897)
Bridge, the name of a district or principality of Syria near Gilead, between Mount Hermon and the Lake of Tiberias (2 Sam. 15:8; 1 Chr. 2:23). The Geshurites probably inhabited the rocky fastness of Argob, the modern Lejah, in the north-east corner of Bashan. In the time of David it was ruled by Talmai, whose daughter he married, and who was the mother of Absalom, who fled to Geshur after the murder of Amnon (2 Sam. 13:37).
Smith's Bible Dictionary (1863)
