'Word of the Lord' in the Bible

Then the Lord turned and looked at Peter. So Peter remembered the word of the Lord, how He had said to him, “Before the rooster crows today, you will deny Me three times.”

Then I remembered the word of the Lord, how He said, ‘John baptized with water, but you will be baptized with the Holy Spirit.’

And this went on for two years, so that all the inhabitants of Asia, both Jews and Greeks, heard the message about the Lord.

but the word of the Lord endures forever.And this is the word that was preached as the gospel to you.
