(i) Tower

(ii) Migdal (4026) - a tower; from a primitive root; to twist (make large).

A tall building erected for defense. Some landowners used towers to protect their crops <Is. 5:2; Matt. 21:33; Mark 12:1>. In the wilderness, towers were used to watch for approaching marauders <2 Kin. 17:9; 2 Chr. 26:10>. In cities towers were part of the walls built for defensive purposes <2 Chr. 14:7; Neh. 3:1>. They were erected at the corners of the wall, beside the city gates, and at intervals along the walls <2 Chr. 26:9>. Watchmen secured the towers <2 Kin. 9:17>, and military machines which threw arrows and stones could be mounted on the massive structures <2 Chr. 26:15>.

The defensive nature of a tower led naturally to figurative references in the Bible. God is pictured as a high, strong tower sheltering His people from the enemy <Ps. 61:3; 144:2; Prov. 18:10>.
