“Take your son, your only son, the one you love, v'lech lecha, and go for yourself to the land of Moriah” (22:2). So begins the command of G-d demanding the sacrifice of Yitzchak. After waiting so long to have a child with Sarah, Abraham was commanded to take his child and return him to G-d. In the face of such a command Abraham was silent—or shall we say speechless?—unable to comprehend the Divine will even as he arose early to carry it out.

"Vayigdal Haish, and the man grew up and grew more and more, until he became very big" (Breisheet 26:13). At first glance, this is a very strange verse. The Torah has just described Yitzchak's and Rivka's move to Gerrar (Yitzchak's place of birth) and the great wealth he acquired there. This move occurred after Eisav's sale of the birthright to Yaakov--an event that happened many years after the Torah, using the same terminology, tells us "vayigdelu hane'arim, and the young men grew up" (25:27).
Judaism eschews extremism. This obligation to be moderate is codified into law by no less an authority than the Rambam; it is, as he points out, "the path of G-d" (Deot 2:7). Furthermore, the goal is not limited to the development of traits of moderation in our attitude towards money, food, or honour; it is to make them second nature to us.
