Maaser Leads to Wealth

Rav Boruch of Mezhibuzh zy”a explains this pasuk by quoting the Gemara (Shabbos 119A) that says that should give maaser in order to become rich. This is hinted to in this verse, which says that one “kaf” (palm) that is full of “ten” – meaning that it gives one-tenth of its earnings for maaser – will be “full of gold”.
