'Again' in the Bible

The sun rises and the sun sets; it hurries away to a place from which it rises again.

All the streams flow into the sea, but the sea is not full, and to the place where the streams flow, there they will flow again.

Whatever exists now has already been, and whatever will be has already been; for God will seek to do again what has occurred in the past.

So I again considered all the oppression that continually occurs on earth. This is what I saw: The oppressed were in tears, but no one was comforting them; no one delivers them from the power of their oppressors.

So I again considered another futile thing on earth:

Again, I observed this on the earth: the race is not always won by the swiftest, the battle is not always won by the strongest; prosperity does not always belong to those who are the wisest, wealth does not always belong to those who are the most discerning, nor does success always come to those with the most knowledge -- for time and chance may overcome them all.
