Robertson's Word Pictures (NT)
For that ye ought to say (anti tou legein umav). "Instead of the saying as to you" (genitive of the articular infinitive with the preposition anti and the accusative of general reference with legein), "instead of your saying."
If the Lord will (ean o kuriov qelh). Condition of the third class with ean and the present active subjunctive (or first aorist active qelesh in some MSS). The proper attitude of mind (Acts 18:21; I Corinthians 4:19; I Corinthians 16:7; Romans 1:19; Philippians 2:19, Philippians 2:24; Hebrews 6:3), not to be uttered always in words like a charm. This Hellenistic formula was common among the ancient heathen, as today among modern Arabs like the Latin deo volente.
This or that (touto h ekeino). Applicable to every act.
