“Aser T’Aser” The Gemara in Taanis learns from this pasuk “Aser Bishvil ShtisAsher” – give Maaser in order that you should become wealthy. The Vilna Gaon says, it is for this reason that the Trop on the word, “T’Aser” is a Zakaif Katon – meaning – the Katon (the poor man) will be Zakaif – stand tall and become wealthy through his Maaser.
