In a strange passage of Talmud, the Rabbis imagine God putting on t'fillin.

The Torah makes a grand pronouncement: Israelites should distance themselves physically and spiritually from neighboring peoples so as not to be tempted to "follow their ways."

Soil P, pH, and salinity are a few things that likely vary by depth in your rootzone. I've started recommending that 20% of putting greens tested be done with a sample divided at the 5 cm depth.

The Torah's famous story of the "scouts" is a pivotal moment - the beginning of the 40 years of wandering in the wilderness. But what did the scouts do wrong?
