1 John 5:21

Keep yourselves [φ υ λ α ξ α τ ε ε α υ τ α]. The exact phrase is not found elsewhere in the New Testament. See 2 Peter 3:17. Rev., rightly, guard. See on 1 Peter 1:4.

Idols [ε ι δ ω λ ω ν]. Strictly, images. The command, however, has apparently the wider Pauline sense, to guard against everything which occupies the place due to God.
