'Word' in the Bible

I am surprised that you are being so quickly turned away from him whose word came to you in the grace of Christ, to good news of a different sort;

For if I [or anyone else should] rebuild [through word or by practice] what I once tore down [the belief that observing the Law is essential for salvation], I prove myself to be a transgressor.

Because if the heritage is by the law, it is no longer dependent on the word of God; but God gave it to Abraham by his word.

For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.

Envy, uncontrolled drinking and feasting, and such things: of which I give you word clearly, even as I did in the past, that they who do such things will have no part in the kingdom of God.

Let him that is taught in the word communicate unto him that teacheth in all good things.
