Regulations within the Covenant (treaty) set forth by the God of the Universe towards the Hebrew people.
King of Israel's duty:
"When he takes the throne of his kingdom, he is to write for himself on a scroll a copy of this law, taken from that of the priests, who are Levites. It is to be with him, and he is to read it all the days of his life so that he may learn to revere the LORD his God and follow carefully all the words of this law and these decrees and not consider himself better than his brothers and turn from the law to the right or to the left. Then he and his descendants will reign a long time over his kingdom in Israel." -Deuteronomy 17:18-20
It is the King's duty to read the law every single day. Why? To remind him that God is the king of the world, not him. Verse 20 implies that it is already a given that authority goes to the head, that is why the king is required to read the law every single day, as a reminder of where his authority lies in the grand scheme of things.
Today's sermon was on this. The speaker commented on how most of the time the Christian's excuse for not reading the Bible daily is due to busyness or not able to find time. Here is an example of someone, the King of Israel, commanded to find time. What do kings do? They run the whole country, negotiate with foreign kingdoms, prepare for battles, fight in wars, and yet the King of Israel is required to read the law every single day. I doubt any of us are busier than a king. I know I'm not.
Just a reminder to me, to stay in the Word daily.
I will not allow my authority over my life go to my head this week. It belongs to God. I gave it to Him, let Him use it as He sees fit.
"It is not necessary that we should discover new ideas in our meditation. It is sufficient and far more important, if the Word, as we read and understand it, penetrates and dwells within us." -Dietrich Bonhoeffer
