Teach Us to Number Our Days
The length of our days is seventy years— or eighty if we are strong— yet their pride is but labor and sorrow, for they quickly pass, and we fly away. Psalm 90:10 · Berean Standard Bible
You might get seventy or eighty years if you're strong, but even that's full of hard work and heartache, and then it's gone. We're not here long, and most of what we labor for is exhausting and temporary.
In an ancient world without modern medicine, this was starkly realistic. Life was shorter and harder. But even today, many people reach seventy or eighty and realize the decades flew by. This verse calls everyone to face that reality head-on.
Moses, making it concrete
This connects to the book of Ecclesiastes, which explores this same theme in depth—vanity, brevity, the question of what actually lasts. It's driving toward the realization that God is what lasts, and relationship with Him is what matters.
Human lifespan reaches seventy or eighty years at most, but these years are consumed by exhausting labor and sorrow, passing away swiftly without lasting value.
This verse provides the concrete existential anchor for the psalm's meditation—the 'three score and ten' (שִׁבְעִים שָׁנָה, shivim shanah) became the biblical standard for human longevity, referenced in later rabbinical literature as a fixed measure. The assessment that these years constitute mere 'labor and sorrow' (עָמָל וָאָוֶן, amal va-aven) echoes Ecclesiastes' evaluation of human striving under the sun. The phrase 'we fly away' (וַעֲפוּ, va-afu) suggests both rapidity and weightlessness—life disperses like scattered birds.
The psalmist addresses the community, quantifying the brevity already established metaphorically.
This stark assessment of human existence became the jumping-off point for medieval and Reformation meditation on proper use of time; it appears in Luther's Small Catechism and structures the spiritual exercises of Ignatian tradition.
8You have set our iniquities before You, our secret sins in the light of Your presence.
9For all our days decline in Your fury; we finish our years with a sigh.
10The length of our days is seventy years— or eighty if we are strong— yet their pride is but labor and sorrow, for they quickly pass, and we fly away.
11Who knows the power of Your anger? Your wrath matches the fear You are due.
12So teach us to number our days, that we may present a heart of wisdom.
