'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;

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 made complete in one word, even in this, Have love for your neighbour as for yourself.

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.

But let him who gets teaching in the word give a part in all good things to his teacher.
