'Sky' in the Bible

But I say to you, there were certainly many widows in Israel in Elijah’s days, when the sky was shut up for three years and six months while a great famine came over all the land.

“A sower went out to sow his seed. As he was sowing, some fell along the path; it was trampled on, and the birds of the sky ate it up.

Jesus told 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 interpret the appearance of the earth and the sky, but why don’t you know how to interpret this time?

It’s like a mustard seed that a man took and sowed in his garden. It grew and became a tree, and the birds of the sky nested in its branches.”

For as the lightning flashes from horizon to horizon and lights up the sky, so the Son of Man will be in His day.
