Hebrews 4:12
12 For wthe word of God is living and xactive, ysharper than any ztwo-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and adiscerning the thoughts and intentions of the heart.
Hebrews 13:17
17 Obey xyour leaders and submit to them, yfor they are keeping watch over your souls, as those who will have to zgive an account. aLet them do this with joy and not with groaning, for that would be of no advantage to you.
