Heb Hebrews, chapter Epistle to the Hebrews, chapter 4
For the word of God-The Father [is] quick, and powerful, and sharper than any twoedged sword, piercing even to the expounding (dissecting) asunder of soul and Spirit [Ruach], and of the joints and marrow, and [is] a discerner of the thoughts and intents of the heart.Isa 49:2; 1Pe 1:23; 2Co 10:4; Eph 6:17; Rev 1:16
