Isaiah 58:8 - Wesley's Explanatory Notes

Thy light — Happiness and prosperity. Break forth — It shall not only appear, but break forth, dart itself forth, notwithstanding all difficulties, as the sun breaks, and pierces through a cloud. Thy health — Another metaphor to express the same thing. Righteousness — The reward of thy righteousness. Before thee — As the morning — star goes before the sun. The glory — His glorious power and providence. Thy rereward — Thus the angel of his presence secured the Israelites when they came up out of Egypt.
