“Remember these things!
O Jacob!
O Israel!
You are my servant!
I formed you!
You are my servant!
O Israel!
You will not be forgotten by me.
I have swept away your transgressions
Like a cloud.
I have swept away your sins
Like a mist.
Return to me!
I have redeemed you.”
Second Isaiah clearly indicates here that Jacob/Israel is the servant of God since it is repeated twice. They were to remember these things. Yahweh will not forget them, since he formed them. He has swept away their transgressions and sins as if they clouds or mists, here today and gone tomorrow. He wanted them to return to him since he had redeemed them.
