וְאָֽנֹכִי֙ נְטַעְתִּ֣יךְ שֹׂרֵ֔ק כֻּלֹּ֖ה זֶ֣רַע אֱמֶ֑ת וְאֵיךְ֙ נֶהְפַּ֣כְתְּ לִ֔י סוּרֵ֖י הַגֶּ֥פֶן נָכְרִיָּֽה׃
Yet I had planted thee a noble vine, Wholly a right seed; How then art thou turned into the degenerate plant Of a strange vine unto Me?
Rashi on Jeremiah
I planted you a noble vine stock Heb. שורק is the branches of a good vine, that is to say the children of pious and righteous fathers. Its midrashic interpretation is: I planted you שורק. I added for you to the seven commandments of the children of Noah, six hundred and six, as is the numerical value of שורק.
