Derived from nadab ("to volunteer, to offer willingly"), nedabah describes an offering given spontaneously from a generous heart — neither required by law nor fulfilling a vow, but an expression of pure devotion. It stands in contrast to required tithes and vow offerings.
The nedabah is the Old Testament picture of grace-motivated generosity. It cannot be coerced. God loves a nedabah-giver — one who gives freely, not under compulsion (2 Corinthians 9:7). The tabernacle and temple were both built by freewill offerings (Exodus 35:29; 1 Chronicles 29:9). Nedabah reveals the true heart of covenant relationship: when love for God is real, generosity becomes instinctive rather than calculated. The ultimate nedabah is Christ Himself, who laid down His life freely: "I lay it down of my own accord" (John 10:18).
