Revelation 6:10

They cried [ε κ ρ α ζ ο ν]. See on Mark 5:5.

How long [ε ω ς π ο τ ε]. Lit., until when. Compare Zechariah 1:12.

O Lord [ο δ ε σ π ο τ η ς]. See on 2 Peter 2:1. Only here in Revelation. Addressed to God rather than to Christ, and breathing, as Professor Milligan remarks, "the feeling of Old Testament rather than of New Testament relation." Compare Acts 4:24; Jude 1:4.

True [α λ η θ ι ν ο ς]. See on John 1:9; Revelation 3:7.

Judge [κ ρ ι ν ε ι ς]. Originally the verb means to separate; thence the idea of selection : to pick out, and so to discriminate or judge.

Avenge [ε κ δ ι κ ε ι ς]. Compare Luke 18:3; Romans 12:19.

On the earth [ε π ι τ η ς γ η ς]. Earth, in Revelation, is generally to be understood of the ungodly earth.
