John Wesley on Isaiah 60:1

Arise - A word of encouragement accommodated to the Jewish, or Hebrew style, wherein, as by lying down, is described a servile and calamitous condition, chap.47:1, so by rising, and standing up, a recovery out of it, into a free, and prosperous one, as may be seen frequently; Rouze up, intimating her deliverance to be at hand. Here under a type, of Jerusalem's restoration, is displayed the flourishing state of the Gentile - church, under the Messiah. Thy light - Thy flourishing and prosperous state.
