Daas Sofrim states that this prayer is related to the emotion aroused by Yisrael by the sight of the many bodies of water which they saw in Babylon. Water is the symbol of life and of Torah, both give nourishment to creation and spiritual life.
[-MeAm Lo'ez, Perek Shira]
HaShem called upon wisdom by imbuing it with the power to create heaven and earth. By understanding "He created the heavens," for, behold, the heavenly bodies have not strayed from their paths since the day they were created.
The field is a metaphor for man. If unused, wisdom remains a capability that is wasted. Understanding is the mental exertion that processes facts and draws new knowledge from them. Wisdom is mentioned first, for it pertains to the beginning stage, then comes understanding. For where there is no knowledge, there is no understanding; and when there is no understanding, there is no knowledge. We should seek to nurture and grow the spark of wisdom that G-d has given.
[-MeAm Lo'ez, Rabbi Scherman, Perek Shira]
