Hebrews 9:15-22
15 Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant. 16 For where a will is involved, the death of the one who made it must be established. 17 For a will takes effect only at death, since it is not in force as long as the one who made it is alive. 18 Therefore not even the first covenant was inaugurated without blood. 19 For when every commandment of the law had been declared by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, 20 saying, “This is the blood of the covenant that God commanded for you.” 21 And in the same way he sprinkled with the blood both the tent and all the vessels used in worship. 22 Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
Substitutionary? Maybe. The covenant of the Father to the Son and also God to Abraham wasn’t based on substitution, but promise. Redemptive, yes!
Surety...mediator, was based on substitution....strict substitution and guarantee
2 By so much
was Jesus made a surety of a better testament.
23 And they truly were many priests, because they were not suffered to continue by reason of death:
24 But this man, because he continueth ever, hath an unchangeable priesthood.
25 Wherefore he is able also to save them to the uttermost that come unto God by him, s
eeing he ever liveth to make intercession for them.
26 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;

SURETY
shoor'-ti:
This word is used in three different connections or groups:
(1) As a derivative of the word "sure" it means "of a certainty" or "surely."--In
Genesis 15:13 the infinitive absolute of the verb is used to give emphasis to the idea of the verb and is rendered "of a surety." In
Genesis 18:13 the Hebrew 'omnam is translated "of a surety." In
Genesis 26:9 'akh is similarly rendered, and has the force of our "indeed." In
Acts 12:11 alethos, is translated in the King James Version "of a surety," but better in the Revised Version (British and American) "of a truth."
(2) In the sense of security or pledge for a person.--This means that one person may become security for another, that such a one will do a certain thing at a time in the future. Judah was "surety" to his father Jacob that Benjamin would safely return from Egypt (
Genesis 43:9). He pledged his life that the younger brother would return safely. He tells Joseph (
Genesis 44:32) how he had become surety for Benjamin, and offers to become Joseph's slave for the sake of his brother. Job says (
Job 17:3), "Give now a pledge, be surety for me with thyself; who is there that will strike hands with me?" The striking of hands refers to the action or gesture by which the surety or pledge was publicly manifested and thus ratified. Job here beseeches God to become surety for him, to pledge him that some time in the future He will cause Job's innocence to be made known and be acknowledged by God Himself. In
Isaiah 38:14 Hezekiah says, "O Lord, I am oppressed, be thou my surety." He wishes God to give him a pledge of some kind, to go security for him in such a way that he will surely be saved out of his sickness and distress. Jesus is called "the surety (egguos) of a better covenant" (
Hebrews 7:22). Jesus is the pledge or surety that through Him we may obtain the assurance and certainty that a more excellent covenant has been established by God, and are assured also of the truth of the promises connected with it.
(3) It is used to describe the practice of going security for another by striking hands with that person and becoming responsible for money or any object loaned.--The Book of Proverbs unhesitatingly condemns the practice. No mention is made of it in the Mosaic Law, as if the custom were then practically unknown. The Book of Proverbs makes no distinction between a stranger and a neighbor; the person who does such a thing is likened unto an animal caught in a trap. He is exhorted to sleep no more until he has got out of the trap, or freed himself from this obligation (
Proverbs 6:1-5). The wisdom of such advice has been abundantly verified by experience. It does not necessarily preclude certain special cases, where the practice may be justified. The international relationships of the Jews in the period of the monarchy, together with the unsettled condition of the country (
Nehemiah 5:3) and people, needed such commercial strictness. Their trade was mostly in the hands of the Phoenicians and other foreigners, and the pressure of taxation for the payment of foreign tribute, etc., was heavy (
Nehemiah 5:4).
Proverbs 11:15;
17:18 declare one "void of understanding" who thus goes security for another.
Proverbs 20:16 seems to contain an exclamation of contemptuous rebuke for the man who goes security.
Proverbs 22:26;
27:13 contain like admonitions.
At the White Throne Judgment, what happens to those with no mediator, or surety?
