'Resting' in the Bible

For the Lord God, the Holy One of Israel has said this,“In returning [to Me] and rest you shall be saved,In quietness and confident trust is your strength.”But you were not willing,

And the burning sand (mirage) will become a pool [of water]And the thirsty ground springs of water;In the haunt of jackals, where they lay resting,Grass becomes reeds and rushes.
