War

War in the Old Testament is a pervasive reality both historical and theological. Israel took possession of Canaan through military conquest ordered by God (Deuteronomy 7:1–2; Joshua 1:2–9), and subsequent Israelite history involved continuous warfare with surrounding nations. The Mosaic law regulated warfare: declarations were required before siege (Deuteronomy 20:10–12), fruit trees were protected (Deuteronomy 20:19–20), and certain categories of persons were exempt from service (Deuteronomy 20:5–8). Israel's military victories and defeats were theologically interpreted as reflecting the nation's covenant faithfulness or disobedience — a theology most explicitly stated in the covenant blessings and curses of Deuteronomy 28. The New Testament reinterprets the warfare motif: while earthly warfare is not condemned, the primary conflict is spiritual. Paul describes the Christian life with military metaphors — armour of God (Ephesians 6:11–17), good soldier (2 Timothy 2:3–4) — while insisting that "the weapons of our warfare are not carnal, but mighty through God" (2 Corinthians 10:4).
