'Passing' in the Bible

Yet we do speak wisdom among those who are mature; a wisdom, however, not of this age nor of the rulers of this age, who are passing away;

Therefore do not go on passing judgment before the time, but wait until the Lord comes who will both bring to light the things hidden in the darkness and disclose the motives of men’s hearts; and then each man’s praise will come to him from God.

and those who use the world, as though they did not make full use of it; for the form of this world is passing away.

For I do not wish to see you now just in passing; for I hope to remain with you for some time, if the Lord permits.
