Corresponding Greek / Hebrew Entries: The Hebrew equivalent for the ordinal "fifteenth" is not directly listed in Strong's Concordance, as Hebrew ordinals are typically formed by combining the cardinal number with the word for "day" or "month." However, the cardinal number fifteen is represented by the Hebrew word חֲמֵשׁ עֶשְׂרֵה (chamesh esreh), which can be found in contexts such as the description of the Passover and other feasts in the Old Testament.

Usage: The term πεντεκαιδεκάτος is used in the New Testament to specify the fifteenth day of a month, particularly in reference to the Jewish calendar and feasts.

Context: The Greek term πεντεκαιδεκάτος appears in the New Testament in the context of Jewish feasts and calendar events. It is specifically used to denote the fifteenth day of the month, which holds significance in Jewish tradition. For instance, the fifteenth day of the month of Nisan marks the beginning of the Feast of Unleavened Bread, following the Passover. This day is significant as it commemorates the Exodus of the Israelites from Egypt, a pivotal event in Jewish history.

In the New Testament, the term is used to provide chronological context to events surrounding Jesus' life and ministry, particularly those that align with Jewish feasts. The Berean Standard Bible (BSB) provides a clear translation of these occurrences, ensuring that readers understand the timing and significance of these events within the broader narrative of Scripture.

The fifteenth day is also relevant in the context of the Feast of Tabernacles, which begins on the fifteenth day of the seventh month, Tishrei. This feast is a time of rejoicing and remembrance of God's provision during the Israelites' wilderness journey.

Understanding the use of πεντεκαιδεκάτος helps readers appreciate the alignment of New Testament events with Jewish traditions and the fulfillment of Old Testament prophecies through Jesus Christ.
