Luke 19:40

If these shall hold their peace (ean outoi siwphsousin). A condition of the first class, determined as fulfilled. The use of ean rather than ei cuts no figure in the case (see Acts 8:31 ; 1 Thessalonians 3:8 ; 1 John 5:15 ). The kind of condition is determined by the mode which is here indicative. The future tense by its very nature does approximate the aorist subjunctive, but after all it is the indicative. The stones will cry out (oi liqoi kraxousin). A proverb for the impossible happening.
