For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. Hebrews 4:12 KJV
And take the helmet of salvation, and the sword of the Spirit, which is the word of God: Ephesians 6:17 KJV
For this reason take up the full armor of God, so that you may be able to resist in the evil day, and having prepared everything, to take your stand. Ephesians 6:13 CSB
