'Summer' in the Bible

I will strike the winter house with the summer house; and the houses of ivory will perish, and the great houses will have an end," says Yahweh.

Thus the Lord Yahweh showed me: behold, a basket of summer fruit.

He said, "Amos, what do you see?" I said, "A basket of summer fruit." Then Yahweh said to me, "The end has come on my people Israel. I will not again pass by them any more.
