'Covenant of Peace' in the Bible

Wherefore, say, 'Behold, I give unto him my covenant of peace,

Wherefore our elders and all the inhabiters of our country spake to us saying, 'Take victuals with you to serve by the way, and go against them, and say unto them: We are your servants.' Now therefore make a covenant of peace with us.

Moreover, I will make a covenant of peace with them, and drive all evil beasts out of the land: so that they may dwell safely in the wilderness, and sleep in the woods.
