ואל הבקר רץ אברהם, “while Avraham himself ran to the cattle, etc.” He could easily have sent one of his numerous servants to go to the stables and to select the animals for slaughter. After all, we know that he had a minimum of 318 male servants (14,14). He refrained from doing so, however, and went himself, and with accelerated gait, in order to honor his guests. All this in spite of the fact that he was both aged and weakened by the circumcision. The Torah reports all this to round out the picture of Avraham as a generous person.
Sheep, very useful to humanity, need to be cared for by a Loving shepherd, but our Shepherd is often silent. Why is the Shepherd silent?
In anger: to not speak harsh words or to punish.
In mercy: to discipline with silence,
When do we give our Creator our silence, the meditations of our heart? In our grief, in our wordless songs of praise, in our anger, and when words fail us, either our own or those of the siddur.
How do we treat those who remain silent? Not very well. Those without a voice are treated as if they lack humanity. Those who do not speak our language are treated like livestock and have their children stolen.
Maybe we need to hear everyone, so we can hear what God says to us, even when we had believe we only hear silence. That still, small voice, gets shouted down all too often. Maybe God isn't silent, but we aren't listening.
The Cow is shown as an example of mutual support and strength, a true symbiotic relationship. For good pasture, they supply us with milk. If we consider the health of the herd when we need to slaughter cows for their meat and leather, we are considering not just their individual usage, but the survival of the species.
Here, the Cow is referred to as trumpeting "to the God of Yaakov", but not the God of Yisrael. Because Torah students are considered to have a closer relationship with God by traditional Jewish thought, but they can't often support themselves, all Jews have an obligation to help support study. Everyone can praise the God of Yaakov, even if they don't consider themselves to be Torah scholars.
How does anyone begin a quest in Jewish writings? First, they saddle up their donkey. Do they know where they are going? No, but the Donkey does. Donkey subjugates himself to the owner's desires, and is cared for as this example of complete submission.
Beating your donkey is wrong because usually the Donkey will do what you ask.
