Isaiah 26:3-7 New International Version (NIV)
3 You will keep in perfect peace
those whose minds are steadfast,
because they trust in you.
4 Trust in the Lord forever,
for the Lord, the Lord himself, is the Rock eternal.
5 He humbles those who dwell on high,
he lays the lofty city low;
he levels it to the ground
and casts it down to the dust.
6 Feet trample it down—
the feet of the oppressed,
the footsteps of the poor.
7 The path of the righteous is level;
you, the Upright One, make the way of the righteous smooth.
