δεκαδύο

twelve

Definition

The Greek word δεκαδύο is the cardinal number 'twelve'. It functions identically to the English number, denoting a specific quantity or group of twelve items or people. In the New Testament, its primary use is to specify the exact number of a group, most famously the twelve apostles (e.g., Matthew 10:1, Luke 6:13). In its two specific occurrences, it is used to count a group of twelve men in Acts 19:7 and to denote a period of twelve days in Acts 24:11.

Biblical Usage

The word is used only twice in the New Testament, both in the book of Acts. In Acts 19:7, it specifies the number of men who received the Holy Spirit and spoke in tongues after Paul's ministry in Ephesus. In Acts 24:11, Paul uses it to state the short duration ('not more than twelve days') since he went up to Jerusalem to worship, defending his innocence. While rare, its usage aligns with the common biblical pattern where the number twelve signifies a complete or foundational group, echoing the twelve tribes of Israel.

Etymology

The word is a compound formed from δέκα (deka, G1176), meaning 'ten', and δύο (dyo, G1417), meaning 'two'. It is a straightforward numerical construction meaning 'ten and two'. It is a cognate of the more common word for twelve, δώδεκα (dōdeka, G1427), which is used far more frequently in the New Testament.

Semantic Range

While the word itself is a simple number, the quantity 'twelve' carries significant theological symbolism in the Bible. It often represents God's chosen people and divinely appointed order, originating from the twelve sons of Jacob (the tribes of Israel). Jesus intentionally chose twelve apostles (Matthew 10:1), symbolically founding a new Israel. The New Jerusalem in Revelation has twelve gates and twelve foundations (Revelation 21:12-14). Thus, understanding this number helps readers see the continuity between God's covenant with Israel and his new covenant community in the church.

In the ancient Jewish and Greco-Roman world, the number twelve was a common unit for administrative and symbolic groups. For Jews, it was indelibly linked to the twelve tribes, representing the whole nation of Israel. This cultural and religious backdrop makes the choice of twelve apostles a powerful symbolic act, immediately signaling to a Jewish audience that Jesus was constituting a renewed or faithful remnant of God's people.

δώδεκα (dōdeka, G1427) — The more common New Testament word for 'twelve', used in nearly all other instances, including for the apostles.
