Hebrews, Chapter 5, verses 11-14
11 Negligence in the knowledge thereof is reprovedHebrews, Chapter 6, verses 1-8
1 He exhorteth not to fall back from the faith6
6:1 Therefore leaving the principles of the doctrine of Christ - That is, saying no more of them for the present. Let us go on to perfection; not laying again the foundation of repentance from dead works - From open sins, the very first thing to be insisted on. And faith in God - The very next point. So St. Paul in his very first sermon at Lystra, Act 14:15, "Turn from those vanities unto the living God."And when they believed, they were to be baptized with the baptism, not of the Jews, or of John, but of Christ. The next thing was, to lay hands upon them, that they might receive the Holy Ghost: after which they were more fully instructed, touching the resurrection, and the general judgment; called eternal, because the sentence then pronounced is irreversible, and the effects of it remain for ever.
6:3 And this we will do - We will go on to perfection; and so much the more diligently, because,
6:4 It is impossible for those who were once enlightened - With the light of the glorious love of God in Christ. And have tasted the heavenly gift - Remission of sins, sweeter than honey and the honeycomb. And been made partakers of the Holy Ghost - Of the witness and the fruit of he Spirit.
6:5 And have tasted the good word of God - Have had a relish for, and a delight in it. And the powers of the world to come - Which every one tastes, who has an hope full of immortality. Every child that is naturally born, first sees the light, then receives and tastes proper nourishment, and partakes of the things of this world. In like manner, the apostle, comparing spiritual with natural things, speaks of one born of the Spirit, as seeing the light, tasting the sweetness, and partaking of the things "of the world to come."
6:6 And have fallen away - Here is not a supposition, but a plain relation of fact. The apostle here describes the case of those who have cast away both the power and the form of godliness; who have lost both their faith, hope, and love, Heb 6:10, etc , and that wilfully, Heb 10:26.Of these wilful total apostates he declares, it is impossible to renew them again to repentance. (though they were renewed once,) either to the foundation, or anything built thereon. Seeing they crucify the Son of God afresh - They use him with the utmost indignity. And put him to an open shame - Causing his glorious name to be blasphemed.
6:8 That which beareth thorns and briers - Only or chiefly. Is rejected - No more labour is bestowed upon it.Whose end is to be burned - As Jerusalem was shortly after.
Mark, Chapter 10, verses 11-16
1 Christ disputeth with the Pharisees touching divorcement, 13 blesseth children that are brought unto him10
10:11 All polygamy is here totally condemned.
10:12 See note at Mar 10:11
10:13 Mat 19:13.
10:14 Jesus seeing it was much displeased - At their blaming those who were not blame worthy: and endeavouring to hinder the children from receiving a blessing. Of such is the kingdom of God - The members of the kingdom which I am come to set up in the world are such as these, as well as grown persons, of a child - like temper.
10:15 Whosoever shall not receive the kingdom of God as a little child - As totally disclaiming all worthiness and fitness, as if he were but a week old.

5:11 Concerning whom - The apostle here begins an important digression, wherein he reproves, admonishes, and exhorts the Hebrews. We - Preachers of the gospel. Have many things to say, and hard to be explained - Though not so much from the subject - matter, as from your slothfulness in considering, and dulness in apprehending, the things of God.
5:12 Ye have need that one teach you again which are the first principles of religion. Accordingly these are enumerated in the first verse of the ensuing chapter.And have need of milk - The first and plainest doctrines.
5:13 Every one that useth milk - That neither desires, nor can digest, anything else: otherwise strong men use milk; but not milk chiefly, and much less that only. Is unexperienced in the word of righteousness - The sublimer truths of the gospel.Such are all who desire and can digest nothing but the doctrine of justification and imputed righteousness.
5:14 But strong meat - These sublimer truths relating to "perfection," Heb 6:1.Belong to them of full age, who by habit - Habit here signifies strength of spiritual understanding, arising from maturity of spiritual age. By, or in consequence of, this habit they exercise themselves in these things with ease, readiness, cheerfulness, and profit.
