Hebrews, Chapter 6, verses 13-20
13 because God is most sure in his promiseMark, Chapter 9, verses 17-31
14 casteth forth a dumb and deaf spirit, 30 foretelleth his death and resurrection9
9:17 And one of the multitude answering - The scribes gave no answer to our Lord's question. They did not care to repeat what they had said to his disciples. A dumb spirit - A spirit that takes his speech from him.
9:20 When he saw him - When the child saw Christ; when his deliverance was at hand. Immediately the spirit tore him - Made his last grand effort to destroy him. Is it not generally so, before Satan is cast out of a soul, of which he has long had possession?
9:22 If thou canst do any thing - In so desperate a case: Have compassion on us - Me as well as him.
9:23 If thou canst believe - As if he had said, The thing does not turn on my power, but on thy faith. I can do all things: canst thou believe?
9:24 Help thou mine unbelief - Although my faith be so small, that it might rather be termed unbelief, yet help me.
9:25 Thou deaf and dumb spirit - So termed, because he made the child so. When Jesus spake, the devil heard, though the child could not. I command thee - I myself now; not my disciples.
9:26 Having rent him sore - So does even the body sometimes suffer, when God comes to deliver the soul from Satan.
9:30 They passed through Galilee - Though not through the cities, but by them, in the most private ways. He was not willing that any should know it: for he taught his disciples - He wanted to be alone with them some time, in order to instruct them fully concerning his sufferings. The Son of man is delivered - It is as sure as if it were done already. Mat 17:22; Luk 9:44.

6:13 For - Ye have abundant encouragement, seeing no stronger promise could be made than that great promise which God made to Abraham, and in him to us.
6:14 Gen 22:17.
6:15 After he had waited - Thirty years. He obtained the promise - Isaac, the pledge of all the promises.
6:16 Men generally swear by him who is infinitely greater than themselves, and an oath for confirmation, to confirm what is promised or asserted, usually puts an end to all contradiction. This shows that an oath taken in a religious manner is lawful even under the gospel: otherwise the apostle would never have mentioned it with so much honour, as a proper means to confirm the truth
6:17 God interposed by an oath - Amazing condescension!He who is greatest of all acts as if he were a middle person; as if while he swears, he were less than himself, by whom he swears!Thou that hearest the promise, dost thou not yet believe?
6:18 That by two unchangeable things - His promise and his oath, in either, much more in both of which, it was impossible for God to lie, we might have strong consolation - Swallowing up all doubt and fear. Who have fled - After having been tossed by many storms. To lay hold on the hope set before us - On Christ, the object of our hope, and the glory we hope for through him.
6:19 Which hope in Christ we have as an anchor of the soul - Entering into heaven itself, and fixed there. Within theveil - Thus he slides back to the priesthood of Christ.
6:20 A forerunner uses to be less in dignity than those that are to follow him. But it is not so here; for Christ who is gone before us is infinitely superior to us. What an honour is it to believers, to have so glorious a forerunner, now appearing in the presence of God for them.
