Time
The Day: Foundation of Time
The day was the fundamental unit of time measurement in the Bible. From the creation account, the pattern of "evening and morning" established the rhythm of daily life (Genesis 1:5). The Hebrew day ran from sunset to sunset, a convention reflected throughout the Old Testament and still observed in Jewish practice. This reckoning explains why biblical festivals begin at sundown.
The hours of daylight were divided somewhat informally in earlier periods. References to morning, noon, and evening served as general markers. The night was divided into watches — three in the Old Testament period (Judges 7:19; Psalm 90:4; 119:148) and four under the later Roman system (Matthew 14:25; Mark 13:35). The division of the day into twelve hours became standard by New Testament times, as Jesus himself indicated: "Are there not twelve hours in the day?" (John 11:9). These hours varied in length by season, since they divided the actual daylight period equally.
The Week and the Sabbath
The seven-day week is one of the Bible's most distinctive contributions to time-keeping. Unlike the day, month, and year, which correspond to natural astronomical cycles, the week has no astronomical basis. Its origin lies in God's pattern of creation and rest: "In six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy" (Exodus 20:11).
The Sabbath gave the week its defining character. Days were simply numbered — first, second, third — except for the seventh, which bore the name Sabbath. By New Testament times, Friday was called the Day of Preparation (Luke 23:54), and the first day of the week took on special significance as the day of Christ's resurrection (Matthew 28:1; Acts 20:7).
Months, Seasons, and the Year
The month was determined by the moon's phases, with each new moon marking the beginning of a new month. The Hebrew calendar was lunisolar — months followed the moon, but the year was periodically adjusted to stay aligned with the agricultural seasons. Early Israelites used Canaanite month names; after the exile, Babylonian names became standard. The month of Nisan (corresponding roughly to March-April) marked the beginning of the religious year (Exodus 12:2), while the civil year began in Tishri (September-October).
The agricultural year shaped Israel's three great pilgrimage festivals: Passover and Unleavened Bread in the spring, the Feast of Weeks (Pentecost) at the wheat harvest, and the Feast of Tabernacles at the autumn ingathering (Deuteronomy 16:16). These festivals anchored the community's experience of time in both God's acts of redemption and the rhythms of the land He had given them.
The Sabbatical year, observed every seventh year, extended the Sabbath principle to the land itself, which was to lie fallow (Leviticus 25:1-7). The Jubilee year, every fiftieth year, brought comprehensive economic restoration (Leviticus 25:8-17).
God's Sovereignty Over Time
The Bible presents God as the Creator and Lord of time itself. He exists before time (Psalm 90:2), sustains it (Colossians 1:17), and will bring it to its appointed end (Revelation 10:6). His perspective on time differs radically from ours: "With the Lord one day is as a thousand years, and a thousand years as one day" (2 Peter 3:8). This does not mean time is meaningless to God but that He is not constrained by it as we are.
The concept of appointed times runs throughout Scripture. God told Abraham that his descendants would return to Canaan "in the fourth generation" (Genesis 15:16). The prophets spoke of events occurring "at the appointed time" (Habakkuk 2:3; Daniel 11:35). Paul declared that "when the fullness of time had come, God sent forth his Son" (Galatians 4:4), presenting the incarnation as the culmination of centuries of divine preparation.
The Day of the Lord and Eschatological Time
Beyond ordinary time-keeping, the Bible develops a rich theology of eschatological time. The prophets spoke of "the day of the LORD" — a decisive moment when God would intervene in judgment and salvation (Joel 2:31; Amos 5:18-20; Zephaniah 1:14-18). This concept shaped Israel's understanding that history was not cyclical but linear, moving toward a definitive divine purpose.
Jesus declared that "the time is fulfilled, and the kingdom of God is at hand" (Mark 1:15), announcing that the long-awaited day was breaking into the present. The New Testament teaches that believers live in the overlap between "this age" and "the age to come" (Ephesians 1:21), with Christ's first coming inaugurating the new age and his return bringing its completion.
The Bible's final words about time are words of promise and urgency: "Surely I am coming soon" (Revelation 22:20). Time, in Scripture's view, is not a meaningless cycle but a purposeful gift, moving toward the day when God will make all things new.
Biblical Context
Time is addressed from Genesis 1 through Revelation 22. Key passages include the creation narrative (Genesis 1), the institution of the Sabbath (Exodus 20:8-11), the festival calendar (Leviticus 23; Deuteronomy 16), the prophetic day of the Lord (Joel 2; Amos 5), Jesus' announcement of fulfilled time (Mark 1:15), and Paul's theology of the fullness of time (Galatians 4:4; Ephesians 1:10).
Theological Significance
The biblical understanding of time reveals God as sovereign over history, directing events toward His redemptive purposes. The institution of the Sabbath teaches that time belongs to God and must include rest and worship. The prophetic concept of the day of the Lord gives history its moral seriousness and eschatological direction. The incarnation as the 'fullness of time' demonstrates that God works within history, not apart from it. For believers, time is a stewardship — a finite gift to be used wisely in light of eternity.
Historical Background
Israel's time-keeping systems developed in dialogue with surrounding cultures. The Babylonians contributed the seven-day planetary week and many of the post-exilic month names. Egypt used a solar calendar of 365 days. The Romans introduced the Julian calendar in 46 BC, which forms the basis of the modern calendar. Archaeological evidence including sundials, water clocks, and calendar inscriptions illuminates ancient time-keeping practices. The Gezer Calendar, dating to the 10th century BC, provides one of the oldest Hebrew inscriptions and records an agricultural calendar of monthly activities.
