'Sky' in the Bible

Consider the birds of the sky, that they do not sow or reap or gather [produce] into barns, and your heavenly Father feeds them. Are you not worth more than they [are]?

And Jesus said to him, "Foxes have dens and birds of the sky [have] nests, but the Son of Man has no place to lay his head."

{It} is the smallest of all the seeds, but when it is grown it is larger than the garden herbs and becomes a tree, so that the birds of the sky come and nest in its branches."

So he answered [and] said to them, "[When] evening comes you say, '[It will be] fair weather because the sky is red,'

and early in the morning, 'Today [it will be] stormy weather, because the sky is red [and] darkening.' You know how to evaluate correctly the appearance of the sky, but you are not able [to evaluate] the signs of the times.

but when it is sown it grows up and becomes the largest of all the garden herbs, and sends out large branches so that the birds of the sky are able to nest in its shade."

But in truth I say to you, there were many widows in Israel in the days of Elijah, when the sky was shut for three years and six months while a great famine took place over all the land.

"The sower went out to sow his seed, and while he was sowing, {some seed} fell on the side of the path and was trampled under foot, and the birds of the sky devoured it.

And Jesus said to him, "Foxes have dens and birds of the sky [have] nests, but the Son of Man has no place to lay [his] head."

Hypocrites! You know how to evaluate the appearance of the earth and the sky, but how [is it] you do not know how to evaluate this present time?

It is like a mustard seed that a man took [and] sowed in his own garden, and it grew and became a tree, and the birds of the sky nested in its branches."

And as they were staring into the sky [while] he was departing, behold, two men in white clothing stood by them

who also said, "Men {of Galilee}, why do you stand there looking into the sky? This Jesus who was taken up from you into heaven like this will come back in the same way you saw him departing into heaven!"

in which were all the four-footed animals and reptiles of the earth and birds of the sky.

[As I] looked intently into it, I was considering [it], and I saw the four-footed animals of the earth and the wild animals and the reptiles and the birds of the sky.

And he prayed again, and the sky gave rain and the earth produced its fruit.

And the sky was split apart like a scroll that is rolled up, and every mountain and island were moved from their place.

These have the authority to shut the sky, so that {it does not rain} during the days of their prophecy. And they have authority over the waters, to turn them to blood, and to strike the earth with every plague as often as they wish.

And large hailstones, weighing about a hundred pounds, came down from the sky upon people, and the people blasphemed God because of the plague of hail, because the plague of it was very great.
