The Greek noun eniautos refers to a year — particularly a complete seasonal cycle or an appointed period of time. It carries the sense of a full revolution, a completed cycle, emphasizing the purposeful nature of time under God.
Eniautos is the year of divine appointment. In Luke 4:19, Jesus reads from Isaiah 61:2: 'to proclaim the year (eniautos) of the Lord's favor' — and then declares 'Today this scripture is fulfilled in your hearing.' The 'eniautos of the Lord' was the Jubilee year when debts were forgiven, slaves released, and land restored. Jesus declares that His entire ministry inaugurates an eternal Jubilee. Hebrews 9:7 uses eniautos to note that the high priest entered the Most Holy Place 'once a year (eniautos)' — a limitation that Christ's once-for-all sacrifice eliminated. James 4:13 warns against planning a full year (eniautos) without acknowledging God's sovereignty over time. Every year belongs to the Lord.
