In Q: Memento quod <subjunctive> brianpck cited five examples from the Latin Vulgate (Fourth Century). Taking one of these:
"memento quod et ipse servieris in Aegypto et eduxerit te inde Dominus Deus tuus." (Deut. 5:15) =
"Remember both that you have served (as a slave) in Egypt and that the Lord himself, your God, brought you out of that place."
Allen & Greenough p.592: "A subordinate clause takes the subjunctive...[Section 3]...When a reason or explanatory fact is introduced by a relative or by a "quod"...".
Does this explain the use of the (perfect) subjunctive, "eduxerit", in the example?
What if normal indirect speech, "eduxisse", had been deployed?
