or alter the word that went forth from my lips.

Isaiah 51:6

6 bLift up your eyes to the heavens,
and look at the earth beneath;
cfor the heavens vanish like smoke,
the earth will wear out like a garment,
and they who dwell in it will die in like manner;
Or  will die like gnats

ebut my salvation will be forever,
and my righteousness will never be dismayed.
