'Testimonies' in the Bible

They rejected his statutes, and his covenant that he made with their fathers, and his testimonies which he testified to them; and they followed vanity, and became vain, and [went] after the nations that were around them, concerning whom Yahweh had commanded them that they should not do like them.

The king stood by the pillar, and made a covenant before Yahweh, to walk after Yahweh, and to keep his commandments, and his testimonies, and his statutes, with all [his] heart, and all [his] soul, to confirm the words of this covenant that were written in this book: and all the people stood to the covenant.
