Strang's example: David's three options (2 Samuel 24); God decreed what David would choose
He offers an example, saying: the three things God left to David's choice in 2 Samuel 24 were all lawful options; David could rightly pick any of them, since God's leave here was moral and not merely physical.
God left him free to take whichever of the three he liked best, did not confine him to one, and so made no decree that he should choose only one. Yet because God knew in advance what David would choose and took that into account, one may rightly say that God simply decreed that pestilence should come and that seventy thousand men should be killed.
God decreed to carry out whatever David would choose; he had foreseen that David would choose this; so it was this that God decreed to carry out. (Strang, On the Will of God concerning Sin, book 3, chapter 2.)

XI. Verbi causa, inquit, tria ista quae Deus permisit Optioni Davidis capite vigesimo quarto libri secundi Samuelis, omnia erant licita, id est, quodvis eorum potuit David licite eligere. Permissio enim horum Dei respectu non solum fuit Physica, sed etiam moralis. Deus permisit ei liberam optionem, ut quodcunque ex tribus mallet, id eligeret, non restrinxit ad unum, itaque non decrevit ut solum unum eligeret: sed praescius futurae electionis Davidis, ejusque habita ratione, recte dici potest simpliciter decrevisse pestem futuram, & septuaginta millia hominum occisum iri. Deus enim decrevit id efficere quod David electurus erat, hoc autem electurum eum Deus praeviderat; ergo hoc idem efficere Deus decrevit. De voluntate Dei circa peccatum lib. 3. cap. 2.
