Isaiah 49:4-5

49:4 But I thought, “I have worked in vain;

I have expended my energy for absolutely nothing.”

But the Lord will vindicate me;

my God will reward me.

49:5 So now the Lord says,

the one who formed me from birth to be his servant –

he did this to restore Jacob to himself,

so that Israel might be gathered to him;

and I will be honored in the Lord’s sight,

for my God is my source of strength –
