'Testify' in the Bible

To whom do I speak, and testify, and they hear? Lo, their ear is uncircumcised, And they are not able to attend. Lo, a word of Jehovah hath been to them for a reproach, They delight not in it.

O LORD, though our iniquities testify against us, do thou it for thy name's sake: for our backslidings are many; we have sinned against thee.

And I write in a book, and seal, and cause witnesses to testify, and weigh the silver in balances;

Yet Thou hast said unto me, O Lord Jehovah, Buy for thee the field with money, and cause witnesses to testify -- and the city hath been given into the hand of the Chaldeans!'

Fields with money they buy, so as to write in a book, and to seal, and to cause witnesses to testify, in the land of Benjamin, and in suburbs of Jerusalem, and in cities of Judah, and in cities of the hill-country, and in cities of the low country, and in cities of the south, for I turn back their captivity -- an affirmation of Jehovah.'
