'Testimony' in the Bible

The law of Jehovah is perfect, restoring the soul: The testimony of Jehovah is sure, making wise the simple.

For he established a testimony in Jacob, And appointed a law in Israel, Which he commanded our fathers, That they should make them known to their children;

He appointed it in Joseph for a testimony, When he went out over the land of Egypt, Where I heard a language that I knew not.

LAMEDH. Quicken me after thy lovingkindness; So shall I observe the testimony of thy mouth.

If thy children will keep my covenant And my testimony that I shall teach them, Their children also shall sit upon thy throne for evermore.
