'Witnesses' in the Bible

I call heaven and earth as witnesses against you today that you will quickly perish from the land you are about to cross the Jordan to possess. You will not live long there, but you will certainly be destroyed.

At the mouth of two witnesses, or three witnesses, shall he that is worthy of death be put to death; but at the mouth of one witness he shall not be put to death.

The hands of the witnesses shall be first upon him to put him to death, and afterward the hands of all the people. So thou shalt put the evil away from among you.

One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.

and they are to make this declaration: "Our hands didn't shed this blood, nor were we witnesses to the crime.

I call heaven and earth as witnesses against you today that I have set before you life and death, blessing and curse. Choose life so that you and your descendants may live,

Assemble all your tribal elders and officers before me so that I may speak these words directly to them and call heaven and earth as witnesses against them.
