In Tehillim 1:1, the verse begins with "ashrei ha'ish," happy is the man. According to Rabbi Yonantan, the man is Avraham, who did not associate himself with the dor haflaga, the people of Sodom and the Philistines. A similar verse in Tehillim 112:1 employs the same phrase "ashrei ish" who fears God. Why is the masculine form used and not the feminine? Two explanations are offered: happy is the person who repents when still young or happy is the person who can control one's evil inclination like a man, i.e., a warrior overcoming his enemies. The continuation of the verse is, "He delights in God's mitzvot." This is explained as one who does mitzvot for the sake of doing a mitzva and not for receiving a reward.

In Tehillim 1:1-2, the verse says that instead of being with evildoers, happy is the person who desires the Torah of God. Rebbi derives from this verse that a person can only learn Torah from the parts of the Torah that one desires to study. Rava extrapolates the verse in the same way and derives other concepts about stages of learning Torah and best practices of learning Torah from these verses and others.

What are the rewards received for learning Torah?

The Mishna forbids building the area in the bathhouse that was built for an idol. Rabbi Elazar in the name of Rabbi Yochanan explains that if one got paid, the money is permitted for use. How is this explained?

The Mishna does not permit making jewelry for idol worship, but Rabbi Eliezer rules that one could get paid for doing that.

Since one cannot sell land to gentiles in Israel, one can also not sell items that are attached to the ground, unless they are already detached. Rabbi Yehuda permits them if they are being sold to be detached after the sale.
