'Witnesses' in the Bible

May heaven and earth be my witnesses against you today, that destruction will quickly overtake you, cutting you off from that land which you are going over Jordan to take; your days will not be long in that land, but you will come to a complete end.

On the word of two or three witnesses, a man may be given the punishment of death; but he is not to be put to death on the word of one witness.

The hands of the witnesses will be the first to put him to death, and after them the hands of all the people. So you are to put away the evil from among you.

One witness may not make a statement against a man in relation to any sin or wrongdoing which he has done: on the word of two or three witnesses a question is to be judged.

Let heaven and earth be my witnesses against you this day that I have put before you life and death, a blessing and a curse: so take life for yourselves and for your seed:

Get together before me all those who are in authority in your tribes, and your overseers, so that I may say these things in their hearing, and make heaven and earth my witnesses against them.
