God showed the care he had of his nation by revealing himself to them, and thus showing them the error of those who think that God gave over the rule of this world to the stars, and that he and the angels have no further interest in it. Hence the first commandment is "I am the Lord thy God," which is followed by "You shall have no other gods," "Thou shalt not take the name of the Lord thy God in vain" (Ex. 20, 2ff.). "Remember the Sabbath day" is for the purpose of condemning the belief in the eternity of the world, as is evident from the conclusion, "For in six days the Lord made heaven and earth, the sea, and all that in them is...." (_ib._ 11). "Honor thy father and thy mother" (_ib._ 12) is intended to inculcate the duty of honoring the cause of one's being, including God. Thus the first five commandments all aim to teach the revelation and Providence of God. The rest deal with social and political conduct, especially the last one, "Thou shalt not covet," which is important in the preservation of society. The commandment to love God involves the knowledge of God, for one cannot love what one does not know. A man must know therefore God's attributes and actions. He must be convinced likewise that no evil comes from God, or he cannot love him as he should. He may fear him but not with the proper fear. For there are two kinds of fear, and the one that is commanded is fear of majesty and awe, not fear of punishment. Divine service means not merely prayer three times a day, but constant thought of God. To develop and train this thought of God in us we are commanded to put on phylacteries and fringes, and to fasten the "mezuzah" to our door posts. For the same reason we celebrate the festivals of Passover, Tabernacles, Hanukkah and Purim, as a remembrance of God's benefits to our people. All these observances are ultimately based upon the duty of thanking our benefactor, which is part of justice, the highest of the virtues. Among moral virtues we are also commanded to practice suppression of anger, and its inculcation is emphasized by making it a divine attribute, "The Lord, the Lord, a God full of compassion and gracious...." (Ex. 34, 6). Other virtues of the same kind are, not to repay evil for evil, not to be jealous, to practice humility like Moses, and so on. In fact all the virtues laid down by ethical philosophers are found better expressed in the Bible. In respect to family virtues, we are bidden to care for and protect the members of our family, wife, children and slaves. Of social virtues we have love of our neighbor, honesty in dealing, just weights and measures, prohibition of interest and of taking a pledge from the poor, returning a find to the loser, and a host of other teachings.
