King James Bible
"In holiness and righteousness before him, all the days of our life."
These paired terms describe the complete devotion God's people offer in response to salvation—holiness emphasizing consecration and purity in worship, while righteousness focuses on just conduct toward others. Together they encompass both vertical and horizontal dimensions of covenant faithfulness. This phrase emphasizes living consciously in God's presence, where all actions and attitudes are transparent to divine scrutiny. It recalls the priestly service in the temple, suggesting that redeemed life itself becomes an act of worship. The temporal scope extends this holy service throughout one's entire lifetime, contrasting with the limited terms of Levitical priests. This permanence reflects the eternal nature of the salvation Zechariah celebrates in his prophecy.
