Job 28:21

"She escapes everyone's gaze. It is not for the indifferent.

And is kept close also from the fowls of the air. [MYSTICAL INTERPRETATION] For in Holy Scripture 'birds' are sometimes given to be understood in a bad sense, and sometimes in a good sense. Since by the birds of the air occasionally the powers of the air are denoted, being hostile to the settled purposes of good men. Whence it is said by the mouth of Truth, And when he sowed, some seeds fell by the wayside, and the fowls of the air came and devoured it; in this way, because evil spirits besetting the minds of men, whilst they bring in bad thoughts, pluck the word of life out of the memory. Hence again it is said to a certain rich man full of proud thoughts; the foxes have holes, and the birds of the air have nests, but the Son of Man hath not where to lay His Head. For foxes are very cunning animals, that hide themselves in ditches and caves; and when they face the light, they never run in straight courses, but always by crooked doublings.

I will ascend above the heights of the clouds. I will be like the Most High. Mark how he in flying sought the regions on high with pride. Which same flight also he recommended to the first of human kind as well. For they themselves by flying as it were tried to go above their own selves, when it was told them that they should taste and be like gods. And while they seek after the likeness of the Deity, they lost the blessings of immortality, which same would not by dying have gone into the earth, if they had been willing to stand with humility upon the earth. But, on the other hand, 'the birds of the air' are wont to be put in a good sense, as in the Gospel the Lord, when He was declaring a likeness of the kingdom of…
