'Righteous' in the Bible

And foundest his heart faithful before thee, and madest a covenant with him to give the land of the Canaanites, the Hittites, the Amorites, and the Perizzites, and the Jebusites, and the Girgashites, to give it, I say, to his seed, and hast performed thy words; for thou art righteous:

You are righteous concerning all that has come on us,because You have acted faithfully,while we have acted wickedly.
