'Testimony' in the Bible

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

{To the chief Musician. On Shushan. Testimony. Michtam of David; to teach: when he strove with the Syrians of Mesopotamia, and the Syrians of Zobah, and Joab returned, and smote the Edomites in the valley of salt, twelve thousand.} O God, thou hast cast us off, thou hast scattered us, thou hast been displeased: restore us again.

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 ordained it in Joseph for a testimony, when he went forth over the land of Egypt, where I heard a language that I knew not.

Quicken me according to thy loving-kindness, and I will keep the testimony of thy mouth.

Whither the tribes go up, the tribes of Jah, a testimony to Israel, to give thanks unto the name of Jehovah.
