'Spirit' in the Bible

For the [earthly] fate of the sons of men and the fate of animals is the same. As one dies, so dies the other; indeed, they all have the same breath and there is no preeminence or advantage for man [in and of himself] over an animal, for all is vanity.

Who knows if the spirit of man ascends upward and the spirit of the animal descends downward to the earth?

The end of a matter is better than its beginning;Patience of spirit is better than haughtiness of spirit (pride).

Do not be eager in your heart to be angry,For anger dwells in the heart of fools.

There is no man who has power and authority over the wind to restrain the wind,Nor does he have authority over the day of death;There is no discharge [from service] during time of war,And evil will not rescue those who [actively seek to] practice it.

If the temper of the ruler rises against you, do not leave your post [showing resistance], because composure and calmness prevent great offenses.

Just as you do not know the way and path of the wind or how the bones are formed in the womb of a pregnant woman, even so you do not know the activity of God who makes all things.

then the dust [out of which God made man’s body] will return to the earth as it was, and the spirit will return to God who gave it.
