John Trapp on Hebrews 4:12

Verſe 12. Quick and powerfull] Gr. Lively and energeticall: ſc. In hearts that can tremble at Gods judgements, as David did, Pſal. 119.120. As for hypocrites, the Word Will ranſack them, and give them a very glimpſe of the judgement to come, as it did Faelix, Herod, &c. God ſmiteth the earth with this rod of his mouth, Iſa. 11.4. he daſheth them in the teeth, and maketh them ſpet bloud, as it were; hewing them by his Prophets, and ſlaying them by the words of his mouth, Hoſ. 6.5. Rev. 11.5.

Soul and spirit] See the Note on 1 Theſſ. 5.23.

And is a diſcerner] Gr. A curious Critick judging exactly, and telling tales of the hearers: diſcloſing the words that they ſpeak in their very bed-chambers, as 2 King. 6.12.
