'Word of God' in the Bible

For the word of God is lively and efficacious, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, and of the very joints and marrow, and judging the thoughts and intentions of the heart.

and of the good word of God,

By faith we understand that the worlds were framed by the word of God, for the things which are seen were not made of things which appear.

Remember your guides, who spake the word of God to you; whose faith imitate, considering the happy end of their conversation.
