What are the “weightier matters” of Torah?

“Teacher, which is the great commandment in the Torah?” Yeshua said to him, “‘You shall love the LORD your God with all your heart, with all your soul, and with all your mind. “This is the first and great commandment. “And the second is like it: ‘You shall love your neighbor as yourself. “On these two commandments hang all the Torah and the Prophets.”  Matthew 26: 36-40

Each week we look at the Brit Hadashah reading from the Torah portion and ask “What is the weightier matter we can glean from the reading this week?”
