When Job speaks of a redeemer, we think of Jesus. Though Job lived long before Jesus was born, we know that Jesus was already God’s plan to redeem us. (Eph 1:4)
In ancient Israel, there was also the idea of a family redeemer, the closest relative who had the responsibility of stepping in to help when someone was alone or in trouble. Today we would call this the next of kin. For children, this would be mom or dad. A child who has lost their parents or whose parents are not able to care for them needs someone else to be their redeemer or advocate…to stand with them and for them.
