This Parshah is one of the multiple wonders.
Yitro, a priest of Midian, effectively institutes the tradition of brachot for miracles. “Yitro is not the first person to bless God, but he is the first to offer a bracha in response to a miracle performed for a group (rather than an individual).” Dr. David Ackerman
Parshat Yitro gives us the basis for the whole human morality. Gd commands the human beings to behave in certain ways both toward the Higher Being and toward each other – don’t kill, don’t steal, don’t covet, respect your parents, don’t think that other powers are greater than Gd! However, there is no command governing the behaviour of a human toward oneself – Gd never tells us to be happy.
I am not even sure the word exists in the Torah. Gd does tell us to work, and be joyful, and enjoy the fruit of our labour “You shall eat, and be satisfied, and bless.” (Deuteronomy 8:10) As parents, we can all agree that the commandments given to us at the foot of Mount Sinai are the ones we want our children to adhere to guaranteeing their becoming good and moral human beings. But, don’t we all want them to be happy above everything else? We, really, never want to see our children crying of pain – physical or emotional. So, why does Gd, being our ultimate father never speak about happiness?
