A few quotes from the Rabbi on 'Tzedakah and Healing'
in which he interprets the Priests Blessing as honestly providing for the poor, this being called 'countenance'
It is known that one must try to provide for the poor person before his appeal for support and assistance. It has been said, concerning this, that if a poor person first had to extend his hand, then the letters of the Name will arrive in reverse, and this is termed "hind", while if a person extends his hand to the poor before he [the latter] puts out his hand to take, then will the Name arrive straightforwardly, and this is termed "countenance".
It is also known that peace will come through charity, and has been said, "And the work of righteousness shall be peace". This is what is meant by "The LORD lift up His countenance upon you", that if you achieve bringing the letters of the Name's countenance straightforwardly, He will then give you peace.
And it is also known that it is by the merit of charity that we are redeemed, and that they, of blessed memory, said that the name of the Messiah is like the name of his Master's, as it says 'our just Lord', which explained in Scripture by what follows, 'So shall they put My name' - on the People of Israel, as it were, meaning that the Name of God is carried by the Messiah, who will arrive speedily in our days, and very soon, Amen.
