'Contained' in the Bible

“And behold, I am coming quickly. Blessed (happy, prosperous, to be admired) is the one who heeds and takes to heart and remembers the words of the prophecy [that is, the predictions, consolations, and warnings] contained in this book (scroll).”

But he said to me, “Do not do that. I am a fellow servant with you and your brothers the prophets and with those who heed and remember [the truths contained in] the words of this book. Worship God.”
