Why would we want to go back to living in tents? Rashi explains that this is a reference to our forefather Yaakov, whom the Torah describes as a dweller of tents (Genesis 25:27). This means that, unlike the outdoorsy Esau, Yaakov stayed in the Beis Medrash and studied Torah. Similarly, G-d is telling us through Hoshea that after He does away with the deceitful people (see verses 8-9), He will establish a community of Torah scholars among the people.
