'Testimony' in the Bible

The law of the LORD is perfect, converting the soul: the testimony of the LORD 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:

This he ordained in Joseph for a testimony, when he went out through the land of Egypt: where I heard a language that I understood not.

Quicken me after thy lovingkindness; so shall I keep the testimony of thy mouth.

Whither the tribes go up, the tribes of the LORD, unto the testimony of Israel, to give thanks unto the name of the LORD.

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