Musar zu Dewarim 7:7

ותדבק נפשו בדינה . We find a statement in Bereshit Rabbah 80,7, that three expressions are used to describe G–d's love or attachment for Israel. The expressions are: דביקה, חשיקה, and חפיצה. The first expression is used in Deut. 4,4; the second expression is used in Deut. 7,7; the last expression is used in Malachi 3,12. The Midrash continues that we learn this lesson from this wicked person Shechem, of whom all these three kinds of feelings for Dinah are reported in 34,3-19 [actually the expression ויאהב is also used for his feelings.] Shechem's attachment to Dinah was of a terrestrial nature, designed to gratify his cravings in this world, and he wanted to achieve realization by means of these three kinds of "love."

They further said (Chulin 89a): "'It was not because you were greater than any people that the L-rd desired in you and chose you' (Devarim 7:7) - the Holy One, blessed be He, said to Israel, 'My sons, I desire you because even when I bestow greatness upon you, you humble yourselves before Me. I bestowed greatness upon Avraham, yet he said to Me, 'I am but dust and ashes' (Gen.18:27); Upon Moses and Aharon, yet they said: 'And we are nothing' (Ex.16:7); upon David, yet he said: 'I am but a worm and no man' (Tehilim 22:7)"

To what is this similar? To a pig-herder who rose to become the king. As long as he remembers his early days, it will be impossible for him to become arrogant. Likewise, when one considers that at the end of all his greatness, he will return to the earth to be food for maggots, all the more so will his pride be submitted and his roaring arrogance quieted. For what is his good and his greatness if his end is shame and dishonor?
