'Summer' in the Bible

And I will send destruction on the winter house with the summer house; the ivory houses will be falling down and the great houses will come to an end, says the Lord.

This is what the Lord God let me see: and I saw a basket of summer fruit.

And he said, Amos, what do you see? And I said, A basket of summer fruit. Then the Lord said to me, The end has come to my people Israel; never again will my eyes be shut to their sin.
