Rutherford: God knows the Keilah and Tyre conditionals by free knowledge in a predetermining decree
Rutherford himself, lately professor of theology at the University of St Andrews, also a learned and subtle man, uses the same principle. He states that God knew by free knowledge, in a predetermining decree, that the people of Keilah would hand David over to Saul if he had stayed with them, that the Tyrians would have repented if they had seen the signs, and other things of the kind.
By that decree, he says, God absolutely fixed beforehand the sequence of all possible beings. 'This certainly,' he says, 'belongs to the wonderful providence of God, whose will is undetermined and suspended toward no beings, whether actual or possible.'

XXXV. Et certe Retorfortis ille, nuper in Academia Andreapolitana, Theologiae Professor, Vir quoque Doctus & subtilis, eodem utens principio, affirmat Keilitas Davidem in manus Saulis tradituros, si apud eos permansisset, & Tyrios acturos poenitentiam, si signa vidissent, & alia ejusmodi, Deus cognovit scientia libera in decreto praedeterminante, quo concatenationem entium omnium possibilium absolute praedefinivit, quod certe, inquit, spectat ad admirandam Dei providentiam, cujus voluntas ad nulla entia, vel quae actu sunt, vel quae possibilia sunt, est indeterminata & suspensa.
