The Bible forbids a nation from having the apparatus necessary to launch a foreign war. Deut. 17:6 forbids the king from “multiplying horses to himself,” which in that culture banned the capability of conducting foreign war because a cavalry was needed to invade foreign lands, whereas an infantry (Exo. 17:9-10, Num. 1:2-3) was more than adequate to defend the homeland from outside attacks.
