Migdol

Boyd’s Bible Dictionary:

(tower). Place in Egypt (Ex. 14:2; {vi 4768-4769}Num. 33:7-8). Perhaps same in ({vi 20012;20060}Jer. 44:1; 46:14).

Concise Bible Dictionary:

Place near to which the Israelites crossed the Red Sea (Ex. 14:2; Num. 33:7). Apparently distinct from another Migdol in the north of Egypt (Jer. 44:1; Jer. 46:14). In Ezekiel 29:10, margin, “from Migdol to Syene” implies from north to south of Egypt.
