Avodah Zara 19: Learning Torah; Selling Plants Attached to the Ground

Today's daf teaches a number of verses or parables and justifies their meanings.  Briefly, we learn:

• it is best to study Torah slowly over time
• either one study's one's heart's dire or one receives one's heart's reply when studying
• Torah study should be split into three parts: Torah, Mishna, and commentary
• perseverance is a large part of Torah study
• we cannot receive money from any form of work regarding idolatry
• a new Mishna: Should different items be sold to idolaters?
• The rabbis discuss selling plants that are attached to the ground
