That the Jews would lose while we should receive the bread and the cup of Christ and all His grace, and that the new name of Christians should be blessed in the earth
In Isaiah: “Thus says the Lord, Behold, they who serve me shall eat, but you shall be hungry: behold, they who serve me shall drink, but you shall be thirsty: behold, they who serve me shall rejoice, but you shall be confounded; the Lord shall slay you. But to those who serve me a new name shall be named, which shall be blessed in the earth.” Also in the same place: “Therefore shall He lift up an ensign to the nations which are afar off, and He will draw them from the end of the earth; and, behold, they shall come swiftly with lightness; they shall not hunger nor thirst.” Also in the same place: “Behold, therefore, the Ruler, the Lord of Sabaoth, shall take away from Judah and from Jerusalem the healthy man and the strong man, the strength of bread and the strength of water.” Likewise in the thirty-third Psalm: “O taste and see how sweet is the Lord.
Blessed is the man that hopes in Him. Fear the Lord God, all you His saints: for there is no want to them that fear Him. Rich men have wanted and have hungered; but they who seek the Lord shall never want any good thing.” Moreover, in the Gospel according to John, the Lord says: “I am the bread of life: he that comes to me shall not hunger, and he that trusts in me shall never thirst.” Likewise He says in that place: “If any one thirst, let him come and drink. He that believes in me, as the Scripture says, out of his belly shall flow rivers of living water.” Moreover, He says in the same place: “Unless you eat the flesh of the Son of man, and drink His blood, you shall have no life in you.”
