1[165] Gather together, therefore, O soul, what is adequate of itself and suitable, and neither more than sufficient so as to be excessive, nor on the other hand less so as to fall short, that dealing in right measures thou mayest do no wrong. For thou art required also, when making it thy study to cross over from the passions and when sacrificing the Passover, to take the forward step, whose symbol is the lamb, not without measure, for he says “each man shall reckon what suffices for him as a lamb” (Exod. 12:4).

2[166] Both in the case of manna then, and in the case of every boon which God confers upon our race, it is good to take what is fixed by strict measure and reckoning and not that which is above and beyond us; for to do this is to be over-reaching. Let the soul, then, gather the day’s portion for a day (Exod. 16:4), that it may declare not itself but the bountiful God guardian of the good things.
