The Greek verb dēloō means 'to make clear,' 'to declare,' 'to show plainly,' or 'to reveal.' It is used in contexts of divine revelation, apostolic proclamation, and prophetic disclosure. Peter uses it in 1 Peter 1:11 to describe how the Spirit of Christ was 'indicating' (dēloō) sufferings to come.
Dēloō captures the idea of making something previously hidden or unclear fully manifest. In 1 Corinthians 1:11, it refers to information being clearly reported to Paul; in 1 Peter 1:11, it describes the prophetic Spirit's work of advance disclosure. This word family connects to the concept of divine revelation as progressive and purposeful — God does not leave His people in darkness but continually makes His purposes clear through Scripture, Spirit, and apostolic teaching.
