And this will be for a sign to you on your hand and for a mark on your brow, so that the law of the Lord may be in your mouth: for with a strong hand the Lord took you out of Egypt.
And I will give them one heart and one way, so that they may go on in the worship of me for ever, for their good and the good of their children after them:
Moses said to them, Let the words which I have said to you today go deep into your hearts, and give orders to your children to do every word of this law.
Let the word of Christ be in you in all wealth of wisdom; teaching and helping one another with songs of praise and holy words, making melody to God with grace in your hearts.
For this reason there is the more need for us to give attention to the things which have come to our ears, for fear that by chance we might be slipping away.
For this reason I will be ready at all times to keep your memory of these things awake, though you have the knowledge of them now and are well based in your present faith.
