'Rest' in the Bible

Now I would certainly be lying down in peace;I would be asleep.Then I would be at rest

There the wicked cease to make trouble,and there the weary find rest.

I cannot relax or be still;I have no rest, for trouble comes.

look away from him and let him restso that he can enjoy his day like a hired hand.

My roots will have access to water,and the dew will rest on my branches all night.

I am churning within and cannot rest;days of suffering confront me.
