Ps 95:8-96:1
8 "Don't turn a deaf ear as in the Bitter Uprising, As on the day of the Wilderness Test, 9 when your ancestors turned and put me to the test. 10 For forty years they watched me at work among them, as over and over they tried my patience. And I was provoked — oh, was I provoked! 'Can't they keep their minds on God for five minutes? Do they simply refuse to walk down my road?' 11 Exasperated, I exploded, 'They'll never get where they're headed, never be able to sit down and rest.'"

This is about the Israelites.
