The Greek numeral deka means ten. It is foundational in Greek numerical vocabulary and appears throughout the New Testament in parables, apocalyptic visions, and narrative contexts. Ten often functions as a symbol of completeness or of testing.
The number ten carries deep theological resonance. The Ten Commandments (Exodus 20; Deuteronomy 5) are the foundational covenant document of Israel. Jesus's parables feature ten virgins (Matthew 25:1) and ten minas (Luke 19:13), using the number to denote a full, representative group. The book of Revelation's ten horns and ten diadems (Revelation 12:3; 13:1; 17:12) represent complete but temporary worldly power arrayed against God. In Jewish tradition, ten also signals a quorum (minyan). The number embodies completeness, accountability, and the fullness of responsibility.
