'Witness' in the Bible

I call heaven and earth to witness against you this day, that you shall soon utterly perish from off the land whereunto you go over the Jordan to possess it; you shall not prolong your days on it, but shall utterly be destroyed.

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

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

If an unrighteous witness rise up against any man to testify against him of wrongdoing,

and the judges shall make diligent inquisition: and, behold, if the witness is a false witness, and has testified falsely against his brother;

I call heaven and earth to witness against you this day, that I have set before you life and death, the blessing and the curse: therefore choose life, that you may live, you and your seed;

"Now therefore write this song for yourselves, and teach it to the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.

It shall happen, when many evils and troubles are come on them, that this song shall testify before them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they frame this day, before I have brought them into the land which I swore."

"Take this book of the law, and put it by the side of the ark of the covenant of Yahweh your God, that it may be there for a witness against you.

Assemble to me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to witness against them.
