Erek refers to an assessed value, estimate, or valuation — the determined worth of something for purposes of redemption or vow fulfillment. It appears predominantly in Leviticus 27, where various persons, animals, and property are assigned erkim (valuations) for purposes of temple dedication and redemption. A person dedicated to the Lord could be redeemed by paying the erek — the assessed redemption price, which varied by age and gender.
Leviticus 27's system of valuations reveals that God has ordered a structure of redemption — every person and thing dedicated to Him has an erek, a set price by which it can be redeemed. Theologically, this foreshadows the most important valuation question: What is the price to redeem a human soul? The answer of the New Testament is staggering — the blood of Christ (1 Pet 1:18-19). Paul uses pricing language: 'You were bought at a price' (1 Cor 6:20). God did not assess us as worthless; He assigned to us an infinite erek — worth the death of His own Son.
