Esias 58:10

10 and thou give bread to the hungry from thy heart, and satisfy the afflicted soul; then shall thy light spring up in darkness, and thy darkness as noon-day:

Esias 58:10 In-Context

8 Then shall thy light break forth as the morning, and thy health shall speedily spring forth: and thy righteousness shall go before thee, and the glory of God shall compass thee.
9 Then shalt thou cry, and God shall hearken to thee; while thou art yet speaking he will say, Behold, I am here. If thou remove from thee the band, and the stretching forth of the hands, and murmuring speech;
10 and thou give bread to the hungry from thy heart, and satisfy the afflicted soul; then shall thy light spring up in darkness, and thy darkness as noon-day:
11 and thy God shall be with thee continually, and thou shalt be satisfied according as thy soul desires; and thy bones shall be made fat, and shall be as a well-watered garden, and as a fountain which the water has not failed.
12 And thy old waste desert shall be built up, and thy foundations shall last through all generations; and thou shalt be called a repairer of breaches, and thou shalt cause thy paths between to be in peace.
