(Gen. 1:1) In the beginning (Be-REiShYT) – this is Israel, as is written: (Jer. 2:3) Holy is Israel to Y”Y, the ‘reishyt’ (first) of His produce... – ‘first’ without any other admixture. And because he is holy, he has no grafting of any other type.
And because he Israel is holy, the fruit the drop requires preservation for his true female partner, which is the letter Hei ה. And because of this, the ‘first’ tevu-at (produce-of) and the letter ה Hei, it Israel has no defect. It is this that is written: (Gen. 25:27) And Jacob was a perfect (tam) man... – meaning he had no refuse. [It is required to be preserved for:] This ‘fruit’ is fit for a King, and therefore: (Jer. 2:3)... all who eat of it will be rendered guilty, evil shall come upon them, says Y”Y.
