    — Psalm 90:12 (KJV)
    Read Chapter

    Introduction

    Moses' prayer in Psalm 90:12 is one of the most practical requests in Scripture: teach us to count our days rightly so we live wisely. Numbering our days is not morbid — it's liberating.

    Historical Context

    Psalm 90 is attributed to Moses — the oldest psalm. Moses had watched an entire generation die in the wilderness over 40 years. He understood human mortality intimately.

    Original Language Insights

    'Number' (manah) — to count, to reckon. Precise accounting of what you have so you can steward it wisely.

    'Apply' (bo) — to bring, to cause to enter. Literally, 'cause wisdom to enter our hearts.'

    'Wisdom' (chokmah) — practical skill for living, applied truth.

    Theological Significance

    Wisdom begins with mortality awareness. When you understand your days are numbered, you prioritize differently. The prayer 'teach us' acknowledges this perspective doesn't come naturally.

    Practical Application

    Calculate your probable remaining days. Evaluate how you spend your time against this reality. Live with eternity in view — invest limited time in things with unlimited significance.

    Prayer Response

    Lord, teach me to number my days — not with anxiety but with wisdom. Help me invest my limited time in things with unlimited significance. Amen.

    Frequently Asked Questions

    Isn't focusing on death morbid?
