When a person approaches sanctity or studies Torah in depth must strengthen him or herself even more, and make the effort to give charity. For charity opens the fountains of wisdom; just as one thus opens the eyes of the poor so does the way to wisdom open.
We can, in this way, understand what is written in the text, "Justice, justice shall you pursue, that you may thrive and inherit the land that the LORD your God is giving you". We know the Torah is called "land", in keeping with the text "Her measure is beyond land". This is what "Justice, justice shall you pursue" means – to give more charity, for in this way we will benefit and "inherit the land" – land being Torah wisdom. In this way, we also learn the intention behind the text " Look to the LORD and keep to His way, and He will raise you high that you may inherit the land;" which refers to giving charity. Just as the merciful and compassionate LORD has mercy on His creatures, you must safeguard His ways as well and have mercy on the poverty-stricken…as it says Scripture, "And all your children shall be disciples of the LORD, And great shall be the peace of your children" – our sages, of blessed memory said that charity is called peace.
