Musar su Genesi 18:6

Likewise, you will observe that all the deeds of the Tzadikim (righteous) are always performed with haste. By Avraham it is written: "And Abraham hastened into the tent to Sarah, and said, make ready quickly three measures of fine meal... And he gave it to the lad and he hastened to prepare it" (Bereishis 18:6-7)

When a man comes to realize as truth the great value of the Mitzvot and the greatness of his obligation in them, his heart will certainly be awakened to the service of G-d and he will not be lax in it.

The second method of explaining these verses is based on Abraham's speculating that these visitors were angels. Thus the meal must be understood as an offering to G–d by Abraham. When Abraham "ran to the cattle," this means he went to prepare a bull for the sacrifice. This is what Vayikra Rabbah 27,9 means when it comments on the paragraph שור או כשב או עז, Leviticus 22,27 that the entire legislation of animal as well as meal offerings and the ability to atone for our sins by means of these animal offerings is due to the patriarchs. In the case of Abraham this is because אל הבקר רץ אברהם, "Abraham ran to the cattle" to select a suitable offering for G–d. The previous verse describing Abraham rushing into the tent to give instructions to Sarah what and how she was to bake, is a reference to the קרבן מנחה, the meal offering. Instead of mentioning a libation of wine, something that usually accompanies such offerings, Abraham took milk and butter. The reason he did so is that milk is conceptually connected to the attribute of Love, חסד, whereas wine is a symbol of the attribute of justice. At this point in Abraham's life the entire emphasis is on the acts of חסד he performs.
