Luke 12:55

Heat [κ α υ σ ω ν]. See on James 1:10; Matthew 20:12.

Discern [δ ο κ ι μ α ζ ε ι ν]. See on trial and tried, 1 Peter 1:7. It means here test or prove. You can test and prove the weather by your signs; but you cannot apply the proof which lies in the signs of the times. Rev., interpret, gives the idea. Wyc., prove.
