From Deuteronomy 17:18-20
And when he sits on the throne of his kingdom, he shall write for himself in a book a copy of this law, approved by the Levitical priests. And it shall be with him, and he shall read in it all the days of his life, that he may learn to fear the Lord his God by keeping all the words of this law and these statutes, and doing them, that his heart may not be lifted up above his brothers, and that he may not turn aside from the commandment, either to the right hand or to the left, so that he may continue long in his kingdom, he and his children, in Israel.
It is required of Israel’s kings to write out their very own copy of the law and to then keep it with them all the days of their life. And not just to make their office bookshelf look impressive. They are to learn from it and act on it, not turning from it in the least. This is a prescription for success in the eyes of God.
We may not be writing out our own text, but make your Bible your own. As you read it, mark it up and make notes. Keep it with you all the days of your life. Let God keep you humble by it, may God also bless you as you dedicate such time and attention to his Word. We are reading all of it because the entirety of the Bible is written for us, and doing so is a kingly pursuit.
