'Summer' in the Bible

I will destroy both the winter and summer houses. The houses filled with ivory will be ruined, the great houses will be swept away." The Lord is speaking!

The sovereign Lord showed me this: I saw a basket of summer fruit.

He said, "What do you see, Amos?" I replied, "A basket of summer fruit." Then the Lord said to me, "The end has come for my people Israel! I will no longer overlook their sins.
