Chasidut su Genesi 49:13

Genesis 49,12. “his eyes are darker red than wine; his ‎teeth are whiter than milk.” [These words clearly ‎are hyperbole, as Yaakov on his deathbed would not indulge in ‎poetry for poetry’s sake. Ed.] ‎
It is an accepted principle that when a human being (Torah ‎observant Jew) is desirous of obtaining the material blessings of ‎this world, he is immediately overcome by the realization that in ‎return for receiving such blessings he must intensify his ‎attachment, ‎דבקות‎, to his Creator Who has provided these ‎blessings for him. Yaakov attempts to put the mind of such ‎people at ease, basing himself on the statement in the Talmud ‎‎Pessachim 112, that even though the calf is very anxious to ‎drink from the milk of its mother, the mother cow is even more ‎anxious to supply the calf with its milk. In this parable the “calf” ‎is the Israelite, and the “mother cow” is the provider of the milk, ‎i.e. G’d. Yaakov describes the overwhelming desire of G’d to ‎bestow His largesse on His people. The satisfaction G’d derives ‎from being able to do this for His “children,” exceeds even the joy ‎of His children when receiving all these blessings.‎
