'Word' in the Bible

and at the appointed time has made known His word and revealed it as His message, through preaching, which was entrusted to me according to the command of God our Savior—

He must hold firmly to the trustworthy word [of God] as it was taught to him, so that he will be able both to give accurate instruction in sound [reliable, error-free] doctrine and to refute those who contradict [it by explaining their error].

to be sensible, pure, makers of a home [where God is honored], good-natured, being subject to their own husbands, so that the word of God will not be dishonored.
