Bible Dictionary: Terms Beginning with X

Exploring biblical terms starting with "X" reveals names and places from Scripture's historical and genealogical records. Though few in number, these entries connect to the broader narrative of God's work among the nations. Here's your comprehensive guide to essential biblical vocabulary.

Major Biblical Figures

Xerxes

Persian king identified with Ahasuerus in the book of Esther, ruling vast empire from India to Ethiopia, husband of Esther who saved the Jews.

Places and Regions

Xystus

Covered colonnade or portico mentioned in some ancient texts and Apocrypha, referring to covered walkways in Hellenistic architecture.

Additional Terms

Xenodochium

Ancient term for hospice or place of hospitality for strangers, reflecting biblical commands to show hospitality to travelers and foreigners.

Xenophobia

Fear or hatred of strangers and foreigners, contrary to biblical commands to love the sojourner and show hospitality to strangers.

Xylon

Greek word meaning "wood" or "tree," used in New Testament referring to the cross as "tree" on which Christ was crucified.

Note on the Letter X:

Biblical terms beginning with "X" are exceptionally rare in English translations because:

1. Hebrew has no "X" sound - The Hebrew alphabet contains no equivalent to the English letter X, so Old Testament names and terms don't naturally begin with this letter.
2. Greek transliteration - Most X-terms come from Greek words transliterated into English, such as "Xylon" (ξύλον) meaning wood or tree.
3. Persian names - Xerxes represents the primary biblical figure whose name begins with X in English, though in Hebrew texts he is called Ahasuerus (אֲחַשְׁוֵרוֹשׁ - Achashverosh).
4. Translation choices - English Bible translations typically render Greek words starting with "X" using their meaning rather than transliteration (e.g., "cross" rather than "xylon," "stranger" rather than "xenos").
5. Limited usage - Technical theological terms and church history terms beginning with X (like "Xystus") rarely appear in standard Bible dictionaries focused on canonical Scripture.

Xerxes (Expanded Entry)

Xerxes I (ruled 486-465 BC), son of Darius the Great, is the Persian king most scholars identify with King Ahasuerus in the book of Esther. His vast empire stretched from India to Ethiopia, encompassing 127 provinces.

Historical significance: Xerxes is known historically for his massive but ultimately unsuccessful invasion of Greece (480-479 BC), including the famous battles of Thermopylae and Salamis.

Biblical narrative: In Esther's account, Xerxes appears as a powerful but temperamental monarch who:

• Divorced Queen Vashti for refusing his summons
• Selected Esther as his new queen through a kingdom-wide search
• Was manipulated by Haman into decreeing Jewish genocide
• Honored Mordecai for uncovering an assassination plot
• Authorized the Jews to defend themselves against their enemies
• Elevated Mordecai to second-in-command of the empire

Theological significance: God's providence worked through this pagan king to preserve the Jewish people from annihilation, demonstrating divine sovereignty over earthly rulers and protection of His covenant people even in exile.

Archaeological evidence: Persian records and Greek historians confirm Xerxes' reign, his military campaigns, and his administrative system, providing historical context for the book of Esther.

Xylon (Expanded Entry)

Greek term (ξύλον) meaning "wood," "timber," or "tree," used in the New Testament with theological significance:

Usage in Scripture:

• Acts 5:30 - "The God of our fathers raised up Jesus, whom ye slew and hanged on a tree (xylon)"
• Acts 10:39 - "whom they slew and hanged on a tree (xylon)"
• Acts 13:29 - "they took him down from the tree (xylon)"
• Galatians 3:13 - "Cursed is every one that hangeth on a tree (xylon)"
• 1 Peter 2:24 - "Who his own self bare our sins in his own body on the tree (xylon)"

Theological significance: The use of "xylon" (tree) rather than "stauros" (cross) in these passages deliberately connects Christ's crucifixion to Deuteronomy 21:23: "he that is hanged is accursed of God." This emphasizes that Christ became a curse for us, bearing our sins on the tree.

Symbolism: The tree/wood imagery connects to:

• The Tree of Knowledge in Eden where sin entered
• The cross (wooden instrument) where sin was atoned
• The Tree of Life in Revelation representing eternal life restored

Revelation usage: In Revelation 2:7 and 22:2, 14, "xylon" refers to the "tree of life," showing restoration of what was lost in Eden through Christ's death on the "tree."

Additional Greek X-Terms in Biblical Context

Xenos (ξένος)

Meaning: Stranger, foreigner, alien, guest

Biblical usage:

• Appears in contexts commanding hospitality to strangers
• Matthew 25:35 - "I was a stranger (xenos) and you took me in"
• Hebrews 13:2 - "Be not forgetful to entertain strangers (xenos)"
• Related to "xenodocheo" (showing hospitality)

Theological application: Believers are called to be "xenophiles" (lover of strangers) rather than xenophobes, reflecting God's love for sojourners and remembering that Christians are themselves strangers and pilgrims on earth.

Xestes (ξέστης)

Meaning: A Roman liquid measure, approximately a pint

Biblical usage:

• Mark 7:4 (in some manuscripts) - referring to washing of "pots" or vessels
• Technical term for measuring containers used in first-century Jewish purification rituals

Christos (Χριστός - begins with Chi 'X' in Greek)

Note: While "Christ" in English begins with 'C', the Greek Χριστός begins with the letter Chi (X), which is why the ancient abbreviation for Christ was X or XP (Chi-Rho).

Significance of the X symbol:

• "Xmas" uses X as abbreviation for Christ (from Greek Chi)
• Early Christian symbol Chi-Rho (☧) combined X (Chi) and P (Rho)
• Not a modern secularization but ancient Christian practice

Historical and Linguistic Notes

The IHS and XP Symbols:

• XP (Chi-Rho): First two letters of ΧΡΙΣΤΟΣ (Christos) in Greek
• IHS: First three letters of ΙΗΣΟΥΣ (Iesous/Jesus) in Greek
• Both appear in early Christian art and manuscripts

Greek Alphabet Connection: The Greek letter Chi (Χ, χ) is transliterated as "X" or "Ch" in English, creating interesting linguistic bridges:

• Christ = Χριστός (Christos)
• Christian = Χριστιανός (Christianos)
• Antichrist = Ἀντίχριστος (Antichristos)

Names with X in Greek Form

Alexandros (Ἀλέξανδρος - Alexander)

Several biblical figures named Alexander, Greek name meaning "defender of men":

• Alexander the Great - Though not directly named, his empire's influence pervades the New Testament era
• Alexander the coppersmith (2 Timothy 4:14) - Did Paul much harm
• Alexander of Cyrene (Mark 15:21) - Son of Simon who carried Jesus' cross
• Alexander in Acts 19:33 - Jewish man put forward during Ephesian riot

Apollonios/Apollonius

Greek name appearing in Apocryphal literature, related to the god Apollo, representing Hellenistic influence on Jewish culture.

Practical Application for Bible Study:

When encountering limited entries for certain letters, consider:

1. Cross-referencing - Look up related terms under more common letters
2. Language study - Investigate original Hebrew, Greek, and Aramaic terms
3. Historical context - Research the cultural and historical background
4. Theological connections - Link concepts across Scripture's unified message
5. Word studies - Use concordances to trace word usage throughout the Bible

The scarcity of X-terms in English Bibles reminds us that Scripture was written in Hebrew, Aramaic, and Greek, requiring careful translation work to bring God's Word into every language. The few X-terms that exist often represent transliteration choices or technical terminology from the original languages.
