Deuteronomy 32:44-47

Moses came and recited all the words of this song in the hearing of the people, he and Joshua son of Nun. When Moses had finished saying all these words to all Israel, he said, “Take to heart all these words to which I give witness today and urgently command your children to put them into practice, every single word of this Revelation. Yes. This is no small matter for you; it’s your life. In keeping this word you’ll have a good and long life in this land that you’re crossing the Jordan to possess.”
