'Testimony' in the Bible

Bind up the testimony, Seal the law among My disciples.

To the law and to the testimony! If not, let them say after this manner, 'That there is no dawn to it.'

And it hath been for a sign and for a testimony, To Jehovah of Hosts in the land of Egypt, For they cry unto Jehovah from the face of oppressors, And He sendeth to them a saviour, Even a great one, and hath delivered them.
