Isaiah 48:17-18
17 Thus says the Lord,
your Redeemer, the Holy One of Israel:
“I am the Lord your God,
who teaches you to profit,
who leads you in the way you should go.
18 Oh that you had paid attention to my commandments!
Then your peace would have been like a river,
and your righteousness like the waves of the sea;
Isaiah 26:3-4
3 You keep him in perfect peace
whose mind is stayed on you,
because he trusts in you.
4 Trust in the Lord forever,
for the Lord God is an everlasting rock.
