Corresponding Greek / Hebrew Entries: The concept of "tomorrow" in the Hebrew Bible is often represented by the word מָחָר (machar), Strong's Hebrew Number 4279. This term similarly denotes the day following the present one and is used in various contexts throughout the Old Testament to discuss future events or plans.

Usage: The word αὔριον appears in the New Testament to denote a future time, specifically the day after the present one. It is used in contexts where planning, anticipation, or future events are discussed.

Context: The Greek word αὔριον is used in the New Testament to express the concept of the day following the current one, often in the context of planning or considering future events. It appears in several passages, highlighting the human tendency to plan for the future while also emphasizing the uncertainty of life and the importance of trusting in God's providence.

In Matthew 6:34, Jesus instructs His followers, "Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own." Here, αὔριον is used to remind believers of the futility of worrying about the future, encouraging them to focus on the present and rely on God's provision.

James 4:13-14 also uses αὔριον to caution against presumptuous planning: "Come now, you who say, 'Today or tomorrow we will go to this or that city, spend a year there, carry on business, and make a profit.' You do not even know what will happen tomorrow! What is your life? You are a mist that appears for a little while and then vanishes." This passage underscores the transient nature of human life and the need for humility and dependence on God's will.

The use of αὔριον in these contexts serves as a theological reminder of the limitations of human foresight and the importance of living in accordance with divine wisdom and guidance.
