Comentario citado sobre Eclesiastés 6:2

And he was building a city. It doesn’t say “and he built” but rather he was building in the present tense, to indicate that he was continuously building all his days and his building was never completed. For this is their foolish way — that anyone who loves earthly possessions like Cain and his companions is forever building and proceeding, and can never complete his building all his days, because he never has enough of what he lacks. If he has one hundred, he desires two hundred, as is well known about the nature of all those who love money. Therefore, he is forever building and going, and all his days he has no rest, but rather is restless and wandering on the earth like Cain who was restless and wandering. So too is every lover of money — restless and wandering, sitting at home little, as most of his days he chases after wealth as if he were hunting a partridge in the hills. He runs with feet like deer through the desert, mountain, and lowland, crossing ocean paths, all the days of his life — these being the nights too, as even at night his heart does not rest. For he will go to all dangerous places to attain what his soul loves; they will seek but not find, and will never reach their goal, rather all their days they are building and going — cities of poverty that endanger their soul and body, leaving for others the wealth and walls which they built and planted. And a sign for this matter: In the alphabet, the letters spelling “poor” are adjacent and follow the letters spelling “money,” indicating that all who love money are forever poor in their mindset. But that which is said The Lord builds Jerusalem (Psalms 147:2) in the present tense can be explained according to what is concluded in the Gemara (Bava Batra 75a): He saw ministering angels who were cutting precious stones and pearls, etc. He said to them, “For whom are these?” They said to him, “The Holy One, Blessed be He, will set them in the gates of Jerusalem, etc.” If so, at all times The Lord builds Jerusalem, and this is easily understood. Similarly, the language of “building” said regarding Cain hints that he was continuously building forever, as it is written A man to whom God will give wealth and possessions, etc., but God will not enable him to eat from it (Ecclesiastes 6:2). Note that “will give” is in the future tense, when it should have said “gave.” Rather, this is its interpretation: Anyone who is not satisfied with what God has granted him and is always seeking what God will give him — more wealth and possessions beyond what he already has — such a person is surely a scoundrel, a miser, and a penny-pincher, and has no control over his own possessions to eat from them, all the more so to give to others.
