Word Origin & History

shield 
O.E. scield, scild, related to sciell (see shell), from P.Gmc. *skeldus (cf. O.N. skjöldr, O.S. skild, M.Du. scilt, Du. schild, Ger. Schild, Goth. skildus), from base *skel- "divide, split, separate," from PIE base *(s)kel- "to cut." Perhaps the notion is of a flat piece of wood made by splitting a log. The verb is from O.E. gescildan. Shield volcano (1911) translates Ger. Schildvulkan (1910).

Bible Dictionary

Shield

used in defensive warfare, varying at different times and under different circumstances in size, form, and material (1 Sam. 17:7; 2 Sam. 1:21; 1 Kings 10:17; 1 Chr. 12:8, 24, 34; Isa. 22:6; Ezek. 39:9; Nahum 2:3). Used figuratively of God and of earthly princes as the defenders of their people (Gen. 15:1; Deut. 33:29; Ps. 33:20; 84:11). Faith is compared to a shield (Eph. 6:16). Shields were usually "anointed" (Isa. 21:5), in order to preserve them, and at the same time make the missiles of the enemy glide off them more easily.
