So Jesus wept over Jerusalem! And had Israel then, or upon the occasion which this Psalm records, hearkened unto the Lord, the temporal prosperity of Israel would have continued. For, I beg the Reader to observe, that in both instances it is of temporal prosperity the Lord evidently speaks. Here it is of feeding them with fine wheat, and honey out of the rock; and there, in Christ's days, it is of preserving Jerusalem from being visited by the destruction of the sword. Luke 19:41-44.
