Shacharuth (שַׁחֲרוּת) refers to the time of dawn or the period of early youth — the fresh, beginning stage of life. It appears only in Ecclesiastes 11:10 in a poignant exhortation to enjoy youth (shacharuth) before it vanishes. The root shachar means dawn or early morning — so shacharuth is the 'dawnhood' of life, emphasizing its beauty, brevity, and gift-character.
Ecclesiastes 11:10 stands as a call to intentional, joyful living in youth — not recklessness, but the recognition that shacharuth is a season given by God that will not return. The New Testament echoes this in the call to 'redeem the time' (Ephesians 5:16). Every morning (shachar) is a grace; every dawn of life is a gift to be offered back to God before it becomes twilight.
The connection between shachar (dawn) and shacharuth (youth) is theologically rich: youth is the dawn of life, and like physical dawn, it moves irreversibly toward noon and evening. Ecclesiastes uses this to motivate wisdom — not pessimism. God's mercies are new every morning (shachar, Lamentations 3:23), and the dawn of a life well-lived is precious to Him.
