'Word' in the Bible

In Him, you also, when you heard the word of truth, the good news of your salvation, and [as a result] believed in Him, were stamped with the seal of the promised Holy Spirit [the One promised by Christ] as owned and protected [by God].

Do not let unwholesome [foul, profane, worthless, vulgar] words ever come out of your mouth, but only such speech as is good for building up others, according to the need and the occasion, so that it will be a blessing to those who hear [you speak].

so that He might sanctify the church, having cleansed her by the washing of water with the word [of God],

And take the helmet of salvation, and the sword of the Spirit, which is the Word of God.
