Hebrews, Chapter 4, verses 14-16
14 By our high priest, Jesus, the Son of God, subject to infirmities, but not sin, 16 we must and may go boldly to the throne of graceHebrews, Chapter 5, verses 1-6
1 The authority and honour of our Saviour's priesthood5
5:1 For every high priest being taken from among men - Is, till he is taken, of the same rank with them. And is appointed - That is, is wont to be appointed. In things pertaining to God - To bring God near to men, and men to God. That he may offer bothgifts - Out of things inanimate, and animal sacrifices.
5:2 Who can have compassion - In proportion to the offence: so the Greek word signifies. On the ignorant - Them that are in error. And the wandering - Them that are in sin. Seeing himself also is compassed with infirmity - Even with sinful infirmity; and so needs the compassion which he shows to others.
5:4 The apostle begins here to treat of the priesthood of Christ. The sum of what he observes concerning it is, Whatever is excellent in the Levitical priesthood is in Christ, and in a more eminent manner; and whatever is wanting in those priests is in him. And no one taketh this honour - The priesthood. To himself, but he that is called of God, as was Aaron - And his posterity, who were all of them called at one and the same time. But it is observable, Aaron did not preach at all; preaching being no part of the priestly office.
5:5 So also Christ glorified not himself to be an high priest - That is, did not take this honour to himself, but received it from him who said, Thou art my Son, this day have I begotten thee - Not, indeed, at the same time; for his generation was from eternity. Psa 2:7.
5:6 Psa 110:4.
Mark, Chapter 8, verses 34-38
34 and exhorteth to patience in persecution for the profession of the gospel8
8:34 And when he called the people - To hear a truth of the last importance, and one that equally concerned them all. Let him deny himself - His own will, in all things small and great, however pleasing, and that continually: And take up his cross - Embrace the will of God, however painful, daily, hourly,continually. Thus only can he follow me in holiness to glory.
8:35 Mat 16:25; Luk 9:24; Luk 17:33; Joh 12:25.
8:38 Whosoever shall be ashamed of me and of my words - That is, avowing whatever I have said (particularly of self denial and the daily cross) both by word and action. Mat 10:32; Luk 9:26; Luk 12:8.

9:1 Till they see the kingdom of God coming with power - So it began to do at the day of pentecost, when three thousand were converted to God at once.

4:14 Having therefore a great high priest - Great indeed, being the eternal Son of God, that is passed through the heavens - As the Jewish high priest passed through the veil into the holy ofholies, carrying with him the blood of the sacrifices, on the yearly day of atonement; so our great high priest went once for all through the visible heavens, with the virtue of his own blood, into the immediate presence God.
4:15 He sympathizes with us even in our innocent infirmities, wants, weaknesses, miseries, dangers. Yet without sin - And, therefore, is indisputably able to preserve us from it in all our temptations.
4:16 Let us therefore come boldly - Without any doubt or fear.Unto the throne of God, our reconciled Father, even his throne of grace - Grace erected it, and reigns there, and dispenses all blessings in a way of mere, unmerited favour.
