The Tenth Day of the Seventh Month: A Sabbath day. Should We Assume Which Calendar God Meant?

Leviticus 23: 26-32

“²⁶ And the Lord spoke to Moses, saying: ²⁷ “Also the tenth day of this seventh month shall be the Day of Atonement. It shall be a holy convocation for you; you shall afflict your souls, and offer an offering made by fire to the Lord. ²⁸ And you shall do no work on that same day, for it is the Day of Atonement, to make atonement for you before the Lord your God. ²⁹ For any person who is not afflicted in soul on that same day shall be cut off from his people. ³⁰ And any person who does any work on that same day, that person I will destroy from among his people. ³¹ You shall do no manner of work; it shall be a statute forever throughout your generations in all your dwellings. ³² It shall be to you a sabbath of solemn rest, and you shall ^]afflict your souls; on the ninth day of the month at evening, from evening to evening, you shall celebrate your sabbath.””

Every year, discussions arise concerning the biblical holy days. One question that deserves careful consideration is this:

When God commanded His people to observe “the tenth day of the seventh month,” did He also command which calendar must always be used?

At first glance, many people answer, “Of course He meant the Hebrew calendar.” But is that actually what the Bible says, or is it an assumption based on historical context?

This article is not intended to argue against those who observe the biblical feasts according to the traditional Hebrew calendar. Rather, it seeks to ask a simple but important question:

Are we saying what God said, or are we saying more than God said?

What the Bible Actually Says

Leviticus 23:27-32 declares:

“Also on the tenth day of this seventh month there shall be a day of atonement…”

Notice what the text explicitly states:

• the tenth day,
• of the seventh month.

Now notice what it does not explicitly state:

• the Hebrew calendar,
• the Jewish calendar,
• a lunar calendar,
• a solar calendar,
• or any perpetual calendrical system that future generations must use.

Many readers immediately assume that the command must refer to the calendar used by ancient Israel. Historically, that is understandable because the command was originally given to Israel.

However, historical context and biblical command are not always identical.

The Difference Between Context and Command

There is no doubt that the Israelites understood the months according to the way they reckoned time in their day. That is part of the historical setting of Leviticus.

But the question is different:

Did God make that historical calendar itself part of the command?

The text never says:

• “According to the calendar of Israel…”
• “According to the lunar reckoning…”
• “According to the calendar presently used among you…”

Those words simply are not there.

If God intended every future generation to use one particular calendar regardless of where or when they lived, He certainly had the ability to say so.

God is not limited by history.

He knew every generation that would ever exist.

He knew kingdoms would rise and fall.

He knew calendars would change.

He knew people would debate chronology.

Yet Scripture records only:

“The tenth day of the seventh month.”

Nothing more.

A God Who Knows Every Generation

God is eternal.

He is not merely the God of Israel in Moses’ day.

He is the God of every generation.

He knew when He inspired Leviticus that later civilizations would use different methods of reckoning time.

He also knew the prophecy recorded in Daniel 7:25 concerning attempts to “change times and law.”

If the precise calendar itself were essential to the command, would it not have been reasonable for God to identify it unmistakably?

Instead, He simply gave the date.

This invites us to ask whether we should be careful not to add details that Scripture itself does not add.

Our position rests on several propositions:

1. God knew all future generations and all calendar systems when He inspired Scripture.
2. God could have specified a particular calendar if He intended one to be mandatory.
3. Since He did not specify one, we should not add that requirement ourselves.
4. Therefore, believers may obey the command by using the calendar by which they presently reckon time where they live, provided the observance is sincere and in humility.

Beware of Assumptions

One of the greatest dangers in biblical interpretation is allowing assumptions to become commandments.

Throughout history, religious traditions have sometimes gained authority equal to—or even greater than—the written Word itself.

Jesus repeatedly warned against replacing God’s commandments with human traditions.

Likewise, Scripture warns us not to add to God’s Word or diminish from it.

Therefore, whenever we claim that God requires something, we should be able to point to where He actually requires it.

A Different Hermeneutical Approach

Our argument raises an interesting hermeneutical question: If God intended His commands to transcend changes in civil calendars, why did He not explicitly identify a perpetual cylindrical standard?

Some believers conclude that because Scripture does not specify a perpetual calendar, the safest approach is to obey the command according to the calendar by which they presently reckon time.

For example, if the civil calendar recognizes today as the tenth day of the seventh month, they observe that day with humility before God.

The emphasis is not on defending a calendar.

The emphasis is on obeying God’s instruction without adding requirements that He Himself did not express.

Whether one agrees with this approach or not, it is internally consistent:

• God commanded a date.
• God did not specify a perpetual calendar.
• Therefore, believers should be cautious about specifying one on God’s behalf.

What About December 25?

This same principle explains why many Christians acknowledge that Scripture never states Jesus was born on December 25.

People may choose to commemorate Christ’s birth on that date as a church tradition, but it should not be presented as a biblical command because the Bible never gives that date.

The issue is not whether traditions may exist.

The issue is whether traditions are presented as if they were Scripture.

A Humble Conclusion

This discussion ultimately reveals two different approaches to interpreting Scripture.

One approach says:

The historical context determines which calendar God intended.

The other says:

Since God did not specify a perpetual calendar, we should not claim one as a divine requirement.

Both positions seek to honor Scripture.

The difference lies in where the burden of proof is placed.

The first asks believers to preserve the historical calendrical context.

The second asks believers to avoid adding requirements that God Himself did not explicitly command.

Whatever conclusion one reaches, one principle should unite us all:

We should strive to distinguish carefully between what God has clearly said and what we infer from the historical setting.

Faithful obedience begins with humble hearts that refuse to alter God’s Word—whether by adding to it or taking away from it. What matters to God is the obedience of His word by a humbled heart which He values rather than the sacrifice.

That echoes a consistent biblical theme. For example:

• “To obey is better than sacrifice” (1 Samuel 15:22).
• “I desire steadfast love and not sacrifice” (Hosea 6:6).
• Jesus quoted that same principle in Matthew 9:13 and 12:7.

When Scripture speaks clearly, we should obey.

When Scripture is silent, we should be careful not to speak for God.

That posture of humility is itself an act of reverence toward the One who inspired His Word.
