Jos 12:21 Taanach, which was allotted to the Manassites in the territory of Issachar, and given up to the Levites (Jos 17:11; Jos 21:25), but was not entirely wrested from the Canaanites (Jdg 1:27), is the present Tell Taënak, an hour and a quarter to the south-east of Lejun, a flat hill sown with corn; whilst the old name has been preserved in the small village of Taânak, at the south-eastern foot of the Tell (see Van de Velde, i. p. 269, and Rob. Pal. iii. p. 156). - Megiddo, which was also allotted to the Manassites in the territory of Issachar, though without the Canaanites having been entirely expelled (Jos 17:11; Jdg 1:27), was fortified by Solomon (1Ki 9:15), and is also well known as the place were Ahaziah died (2Ki 9:27), and where Josiah was beaten and slain by Pharaoh Necho (2Ki 23:29-30; 2Ch 35:20.). Robinson has shown that it was preserved in the Legio of a later time, the present Lejun (Pal. iii. pp. 177ff.; see also Bibl. Res. p. 116).
