Third Function of a Kinsman Redeemer

I came across the theme of "kinsman redeemer" in my study earlier this week. I was familar with the role of a "kinsman redeemer" being twofold: 1) delivering/freeing one from debt, and 2) delivering/freeing one from destitution (ex. Boaz and Ruth). However, Spurgeon eloquently describes the third function of a "kinsman redeemer" among the nation of Israel, which I was not familiar with. The quote below is taken from a sermon Spurgeon preached on April 12, 1863 entitled "I Know that My Redeemer Liveth". In it he describes the "legal avenger" who was also a sort of 'kinsman redeemer". Spurgeon's point is that Christ fulfills the role as our Kinsman Redeemer. What a glorious and rich truth!

(Spurgeon calls the redeemer a "goel", which is the Hebrew transliteration for "redeemer" found in places like Job 19:25.)

"To linger here a moment, there was yet, very conspicuously in the Old Testament, we are informed, a third duty of the goel, which was to avenge the death of his friend. If a person had been slain, the Goel was the avenger of blood; snatching up his sword, he at once pursued the person who had been guilty of bloodshed. So now, let us picture ourselves as being smitten by Death. His arrow has just pierced us to the heart, but in the act of expiring, our lips are able to boast of vengeance, and in the face of the monster we cry, "I know that my Goel liveth." Thou mayst fly, O Death, as rapidly as thou wilt, but no city of refuge can hide thee from him; he will overtake thee; he will lay hold upon thee, O thou skeleton monarch, and he will avenge my blood on thee. I would that I had powers of eloquence to work out this magnificent thought. Chrysostom, or Christmas Evans could picture the flight of the King of Terrors, the pursuit by the Redeemer, the overtaking of the foe, and the slaying of the destroyer. Christ shall certainly avenge himself on Death for all the injury which Death hath done to his beloved kinsmen. Comfort thyself then, O Christian; thou hast ever living, even when thou diest, one who avenges thee, one who has paid the price for thee, and one whose strong arms shall yet set thee free."
