Deuteronomy 30:9-14 New International Version - UK (NIVUK)
9 Then the Lord your God will make you most prosperous in all the work of your hands and in the fruit of your womb, the young of your livestock and the crops of your land. The Lord will again delight in you and make you prosperous, just as he delighted in your ancestors, 10 if you obey the Lord your God and keep his commands and decrees that are written in this Book of the Law and turn to the Lord your God with all your heart and with all your soul.
The offer of life or death
11 Now what I am commanding you today is not too difficult for you or beyond your reach. 12 It is not up in heaven, so that you have to ask, ‘Who will ascend into heaven to get it and proclaim it to us so that we may obey it?’ 13 Nor is it beyond the sea, so that you have to ask, ‘Who will cross the sea to get it and proclaim it to us so that we may obey it?’ 14 No, the word is very near you; it is in your mouth and in your heart so that you may obey it.
