For some reason, searches for Hebrews 4:12 Commentary were coming to this site, so I thought I’d go ahead and post what people were looking for, since the search result was actually taking them elsewhere.
From the Haydock Douay-Rheims Bible – New Testament is Haydock which followed Dr. Troy’s New Testament. I’m unfamiliar with differences.
Hebrews 4:12
12 For the word of God is living and effectual, and more penetrating than any two-edged sword: and reaching unto the division of the soul and the spirit, of the joints also, and the marrow, and is a discerner of the thoughts and intents of the heart.
Haydock Commentary on this is…
Ver. 12. For the word of God is living, &c. Some understand by the word of God, the eternal word, or Son of God: (to whom it may apply all in the 12th and 13th verses) but others rather expound it of the words, promises, and menaces of God, either foretold by the prophets, or preached by the apostles. Wi.–All this language is metaphorical, but perfectly well understood by the Jews. In their sacrifices, the Levites made use of a two-edged knife to separate from the victim what was for God, what was for the priests, and what was for the people. Thus in sacrificing sinners to the justice of God, Jesus Christ, like a two-edged knife, will separate what is for God, and what is for man; i.e. whatever is good or evil in the whole of man’s conduct.
In context..
Hebrews Ch. 4 Haydock NT
The Christian’s rest: we are to enter into it through Jesus Christ.
LET us, therefore, fear, lest perhaps forsaking the promise of entering into his rest, any of you be thought to be wanting. 2 For to us also it hath been declared as well as to them, but the word of hearing did not profit them, not being mixed with the faith of those things which they heard. 3 For we who have believed, shall enter into rest; as he said: “As I have sworn in my wrath: If they shall enter into my rest: and this when the works from the foundation of the world were finished.” (note: reference for this is Psalm 94 or 95 depending on your Bible) 4 For in a certain place he spoke of the seventh day thus: And God rested the seventh day from all his works. 5 And in this place again: “If they shall enter into my rest.”
6 Seeing then it remaineth that some are to enter into it, and they, to whom it was first preached, did not enter in because of unbelief: 7 Again he limiteth a certain day, saying in David: Today, after so long a time, as it is above said: “Today, if you shall hear his voice, harden not your hearts.” 8 For if Jesus had given them rest, he would never have afterwards spoken of another day. 9 There remaineth, therefore, a rest for the people of God. 10 For he who is entered into his rest: he also hath rested from his works, as God from his. 11 Let us hasten, therefore, to enter into that rest: lest any man fall into the same example of unbelief. 12 For the word of God is living and effectual, and more penetrating than any two-edged sword: and reaching unto the divisions of the soul and the spirit, of the joints also, and the marrow, and is a discerner of the thoughts and intents of the heart.
13 Neither is there any creature invisible in his sight: but all things are naked and open to the eyes of him, to whom our speech is. 14 Having, therefore, a great high priest who hath penetrated into the heavens, Jesus, Son of God, let us hold fast our confession. 15 For we have not a high priest, who cannot have compassion on our infirmities: but one temped in all things as we are, without sin. 16 Let us go, therefore, with confidence to the throne of grace: that we may obtain mercy, and find grace in seasonable aid.

That is the same source that I am using. The Bible text quoted above should match the commentary posted on that site. It’s just a lot to type out at the moment. I will probably fill this in at a later date. I have learned a great deal about these texts by transcribing, which is why I do it despite having a free source to look at.
