James 1:3

Trying [δ ο κ ι μ ι ο ν]. Rev., proof; but the American Revisers insist on proving, and rightly. See on 1 Peter 1:7.

Worketh [κ α τ ε ρ γ α ζ ε τ α ι]. The compound verb with kata, down through, indicates accomplishment. The proving will work successfully and thoroughly. This harmonizes with a perfect work, ver. 4.

Patience [υ π ο μ ο ν η ν]. See on 2 Peter 1:6, and James 5:7.
