"No one can practice real benevolence without self-denial. Only by a life of simplicity, self-denial, and close economy is it possible for us to accomplish the work appointed us as Christ's representatives. Pride and worldly ambition must be put out of our hearts. In all our work the principle of unselfishness revealed in Christ's life is to be carried out. Upon the walls of our homes, the pictures, the furnishings, we are to read, “Bring the poor that are cast out to thy house.” On our wardrobes we are to see written, as with the finger of God, “Clothe the naked.” In the dining room, on the table laden with abundant food, we should see traced, “Is it not to deal thy bread to the hungry?” Isaiah 58:7 . MH 206.3"
"Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh?"
Ellen White directly references Isaiah 58:7 in this passage.
