John Wesley on Isaiah 43:10

Ye - You my people are able to witness for me, that I have given you plain demonstrations of my certain knowledge of future events. My servant - Cyrus who is an eminent instance and proof of God's foreknowledge: or, the Messiah, who is the most eminent witness in this cause. Understand - That I am the true God. Nor after me - The gods of the Heathens neither had a being before me nor shall continue after me: whereas the Lord is God from everlasting to everlasting; but these pretenders are but of yesterday. And withal he calls them formed gods, in a way of contempt, and to shew the ridiculousness of their pretence.
