And let us not be weary in well doing: for in due season we shall reap, if we faint not.
Ver. 9. And let us not be weary] Let us not give in as tired jades, εκκακωμεν; hot at hand seldom holds out. Let us not slack our pace in religion, let not our tears begin to freeze; for this, if it doth not lose, yet it may lessen and lighten our crown. Ambrose noteth of the fig tree, that whereas other trees first blossom and then bring forth fruit, in the fig tree it is otherwise, Poma decidunt ut folia succedant, the figs fall off, that leaves may come in their place. So many that begin in fruits, end in leaves, such are they that weary of well doing, lose the things that they have wrought, 2 John 1:8. See Trapp on " 2Jn 1:8 "
For in due season we shall reap] We must not look to sow and reap in a day; as he saith of the Hyperborean people, far north, that they sow shortly after the sun rising with them, and reap before the sun set; that is, because the whole half-year is one continual day with them. (Herosbach de Re Rustica.)
If we faint not] Quaerendi defatigatio turpis est cum id quod quaeritur, sit pulcherrimum, It is a shame to faint in the search of that, which being found will more than pay for the pains of searching. Caleb was not discouraged by the giants, therefore he had Hebron the place of the giants; so those that faint not in the way to heaven shall inherit heaven.
