'Sky' in the Bible

See the birds of the sky, that they don't sow, neither do they reap, nor gather into barns. Your heavenly Father feeds them. Aren't you of much more value than they?

Jesus said to him, "The foxes have holes, and the birds of the sky have nests, but the Son of Man has nowhere to lay his head."

But he answered them, "When it is evening, you say, 'It will be fair weather, for the sky is red.'

In the morning, 'It will be foul weather today, for the sky is red and threatening.' Hypocrites! You know how to discern the appearance of the sky, but you can't discern the signs of the times!

But immediately after the oppression of those days, the sun will be darkened, the moon will not give its light, the stars will fall from the sky, and the powers of the heavens will be shaken;

and then the sign of the Son of Man will appear in the sky. Then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of the sky with power and great glory.

He will send out his angels with a great sound of a trumpet, and they will gather together his chosen ones from the four winds, from one end of the sky to the other.

Jesus said to him, "You have said it. Nevertheless, I tell you, after this you will see the Son of Man sitting at the right hand of Power, and coming on the clouds of the sky."

Behold, there was a great earthquake, for an angel of the Lord descended from the sky, and came and rolled away the stone from the door, and sat on it.
