Ecclesiastes 2:22-23 in the King James Version of the Bible reads, "For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun? For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity."

The book of Ecclesiastes, traditionally attributed to King Solomon, is a reflection on the meaning and purpose of life. These particular verses highlight the existential angst and futility of human effort and toil. The author, known as the Preacher, questions the worth of all the work and striving that human beings engage in during their lives. He observes that despite all their labor, they often find themselves filled with sorrow and grief, unable to find rest even in the stillness of the night. This observation leads him to declare that such a state of being is ultimately vain or meaningless.

One of the key themes in Ecclesiastes 2:22-23 is the theme of futility. The Preacher is grappling with the idea that no matter how hard humans work and strive, their efforts ultimately seem to be in vain. This concept is echoed throughout the book of Ecclesiastes, as the author reflects on the fleeting nature of life and the transience of human accomplishments. The passage also touches on the theme of existential despair, as the Preacher bemoans the inherent sorrows and grief that seem to accompany human existence.

The context of these verses is important to understanding their meaning. In the preceding verses, the Preacher describes all the wealth and earthly pleasures that he accumulated, and yet he found them ultimately unsatisfying. He realized that his pursuit of wealth and pleasure had not brought him the contentment and fulfillment he had hoped for. This leads him to question the value of such pursuits and to reflect on the universal experience of toil and sorrow.

The symbolism in these verses lies in the description of the human condition. The "vexation of the heart" and the "sorrows" and "grief" that fill all of man's days are symbolic of the universal struggles and hardships that people face. The image of the heart not finding rest in the night speaks to the restless and anxious nature of the human soul. The overarching symbolism in these verses is that of the emptiness and futility of human endeavors when separated from a higher meaning or purpose.

In the larger context of the book of Ecclesiastes, these verses ultimately point to the need for a transcendent source of meaning and fulfillment. The Preacher's reflections on the fleeting nature of human accomplishments and the inherent struggles of life lead him to conclude that true satisfaction can only be found in a relationship with God. Throughout the book, the Preacher urges readers to embrace a reverence for God and to find meaning in a life lived in obedience to Him.

In conclusion, Ecclesiastes 2:22-23 offers a poignant reflection on the futility and struggles of human existence. The Preacher's observations about the sorrows and grief that fill our days and the ultimately vain nature of human toil serve as a reminder of the need for a transcendent source of meaning and purpose. Ultimately, these verses point to the importance of seeking fulfillment in a deeper relationship with God rather than in the fleeting pursuits of this world.
