'Testimony' in the Bible

The law of Yahweh [is] perfect, reviving life. The testimony of Yahweh [is] firm, making wise [the] simple.

For he established a testimony in Jacob, and appointed a law in Israel, which he commanded our ancestors to teach to their children,

According to your loyal love preserve me alive, so that I may heed the testimony from your mouth.

where [the] tribes go up, the tribes of Yah [as] a testimony for Israel, to give thanks to the name of Yahweh.
