The answer is: Psalm 90

Psalm 90 - This psalm, attributed to Moses, reflects on the brevity of human life and God’s eternal nature. It contrasts the fleeting existence of man with God’s everlasting presence. Interestingly, it serves as a lament but also calls for wisdom (90:12), paralleling themes found in Ecclesiastes regarding the meaning of life.

Psalm 90 truly stands out in the collection of psalms—not just because it has Moses' name associated with it, but also due to its profound reflections on life and mortality. Here, Moses, often remember for leading the Israelites out of Egypt and receiving the Ten Commandments, channels a contemplative wisdom that resonates through the ages.

When Moses speaks of our days being "brought to an end," he's echoing a recurrent biblical theme: the transience of human existence. This idea is not just unique to Psalms; it also pops up in Ecclesiastes, where the Preacher meticulously ruminates on the "vanity" of earthly pursuits. Isn’t it fascinating that both these ancient texts offer wisdom urging us to value our time here on Earth?

And about wisdom, Psalm 90 urges readers to contemplate that divine awareness could be a tool for deeper understanding, encouraging us to "number our days." The psalm suggests a cosmic perspective on time. God stands beyond what humans can grasp, highlighting a continuum that makes our days seem like mere moments.

Interestingly, Psalm 90 is one of the few psalms without the Exposition of praise. Instead, it feels almost pastoral, seeming to remind us that life can be fleeting, but that doesn’t strip it of its worth. In embracing this reality, perhaps we find the strength to live both fully and meaningfully, grasping the ephemeral nature of our existence while aspiring for wisdom.
