To not steel his heart against the poor: Not to withhold kindness and charity from our brother Israelites — and all the more so, from our relatives — in our knowing the weakness of their situation and that we have the ability to assist them. And about this is it stated (Deuteronomy 15:7), “you shall not steel your heart, and you shall not close your hand from your brother, the destitute one” — meaning to say, do not have the traits of stinginess and villainy rule over you, but rather prepare your heart in every way towards the trait of generosity and pity. And do not think that there will be a lack in your money because of the thing; “as because of [this] thing, God will bless you” (Deuteronomy 15:10). And His blessing for one small instant is better for you than several storehouses of gold and silver.
