(Heb. Yaphlet', יִפְלֵט , Deliverer; Sept. Ι᾿Αφαλήτ ), a son of Heber and great-grandson of Asher; several of his sons are also named ( 1 Chronicles 7:32-33). B.C. between 1856 and 1658. It appears to have been a branch of his descendants (Japhaletites, יִפְלֵטַי , Heb. Yaphleti', Sept. Ι᾿Αφλητί , Vulg. Jephleti, Auth.Version "Japhleti") that are mentioned in  Joshua 16:3 as having settled along the border between Ephraim and Dan, near (north of) the present Jaffa road, apparently east of Beth-horon, possibly at the present Beit Unia. Others, however, regard the name in this locality as a trace of one of the petty tribes of aboriginal Canaanites (compare the Archite, "Archi," in the verse preceding, and in  2 Samuel 15:32; the Ophnite, "Ophni,"  Joshua 18:24).
