Ecclesiastes 1:7

The waters that the earth drank on the first day were not salty. Even if these waters were like the deep on the surface of the earth, they were not yet seas. For it was in the seas that these waters, which were not salty before being gathered together, became salty. When they were sent throughout the entire earth for the earth to drink they were sweet, but when they were gathered into seas on the third day, they became salty, lest they become stagnant due to their being gathered together, and so that they might receive the rivers that enter into them without increasing. For the quantity that a sea requires for nourishment is the measure of the rivers that flow down into it. Rivers flow down into seas lest the heat of the sun dry them up. The saltiness [of the seas] then swallows up [the rivers] lest they increase, rise up and cover the earth. Thus the rivers turn into nothing, as it were, because the saltiness of the sea swallows them up.

The time of your struggle is short. Do not be more inanimate than the earth nor more foolish than [beasts] which lack feeling, for you are endowed with reason and the capacity to administer. Rather, as the Apostle says, "Continue in the things which you have learned and have been assured of" in steadfastness and constant stability. Since these words refer to the divine commands, "be steadfast and unmovable," allow temperance to abide in your life along with firm faith, constant love and stability in every kind of beauty, that you may resemble the earth's eternal stability. If anyone is greedy like the ocean with its expansive, boundedness desire which the inflow of waters cannot satisfy, let one be cured of his illness by looking upon the ocean. In this way he will not transgress his own bounds in the multitude of waters but will retain the same fullness without the addition of more water. In similar fashion pleasures arising from human nature with its present limit cannot expand its gluttonous appetite to keep pace with their great number; rather, the influx [of pleasures] does not cease even though our capacity for enjoyment is limited.

You, whose period of struggle is short, do not become more lifeless than the earth, do not become more unthinking than the insensible, for you are endowed with thought and directed by reason toward life. Instead, as the apostle says, "Continue in the things you have learned and been convinced of," in that steadfast and immoveable stability, since this also is one of the divine commands, that you "be steadfast and immoveable." Let your sobriety abide unshaken, your faith firm, your love constant, your stability in every good thing unmoved, so that the earth in you may stand to eternity. But if any one, yearning for greater possessions and letting his desire become as boundless as a sea, has an insatiable greed for the streams of gain flowing in from every side, let him treat his disease by looking at the real sea. For … the sea does not exceed its boundary with the innumerable streams of water flowing into it but remains at the same volume, just as though it were receiving no new water from streams. In the same way human nature too, restricted by specific limits in the enjoyment of what comes to it, cannot enlarge its appetite to match the extent of its acquisitions; while the intake is endless, the capacity for enjoyment is kept within its set limit.
