Masha. R.
The gift of the Torah is given with love, therefore it is an expression of Divine Mercy, Hesed. At the same time, since there are laws in the Torah, it has the character of the Din-court.
In the formula "Shma Yisrael" the four-letter name of Ashem is mentioned twice, first as an expression of love, Hesed. The second mention of a name is the meaning of the Creator's Common Name. And although they are similar in writing. But the second name is basic, and the first meaning of the Name is only one of the parties to the General.
