'Rest' in the Bible

Now I don't desire to have you unaware, brothers, that I often planned to come to you, and was hindered so far, that I might have some fruit among you also, even as among the rest of the Gentiles.

Indeed you bear the name of a Jew, and rest on the law, and glory in God,

What then? That which Israel seeks for, that he didn't obtain, but the chosen ones obtained it, and the rest were hardened.

that I may come to you in joy through the will of God, and together with you, find rest.
