'Testified' in the Bible

Yet Jehovah testified unto Israel, and unto Judah, by every prophet, and every seer, saying, Turn ye from your evil ways, and keep my commandments and my statutes, according to all the law which I commanded your fathers, and which I sent to you by my servants the prophets.

And they rejected his statutes, and his covenant that he made with their fathers, and his testimonies which he testified unto them; and they followed vanity, and became vain, and went after the nations that were round about them, concerning whom Jehovah had charged them that they should not do like them.
