Torah/Haftorah
The Torah commands us to study the Torah and know it well, and to teach it to others. This is among the most basic tasks of a Believer. Every Believer is obligated to set aside time to study Torah on a daily basis, whether he is old or young, rich or poor, healthy or sick. The obligation lasts throughout one’s life; at no point can someone say that he has completed his obligation to study Torah.
Behold, I have taught you rules and laws, as HaShem my God commanded me, that you will be able to keep them in the land to which you are coming and which you will be occupying. Keep therefore and do them; for this is your wisdom and understanding in the eyes of the nations; they will hear all these statutes, shall say, Surely this great nation is a wise and understanding people. For what nation is so great that they have God so near to them, as HaShem our God is whenever we call upon him? And what nation is so great that they have rules and laws so righteous as all this Torah, which I set before you this day? Deuteronomy 4:5-8
And Moses called all Israel, and said to them, Hear, O Israel, the rules and laws which I speak in your ears this day, that you may learn them, and keep, and do them. Deuteronomy 5:1
Hear, O Israel; HaShem is our God, HaShem is One. And you shall love HaShem your God with all your heart, and with all your soul, and with all your might. And these words, which I command you this day, shall be in your heart; and you shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise up. Deuteronomy 6:4-7
