'Peace' in the Bible

I sent messengers out of the wilderness of Kedemoth to Sihon king of Heshbon with words of peace, saying,

When you draw near to a city to fight against it, then proclaim peace to it.

It shall be, if it makes you answer of peace, and opens to you, then it shall be, that all the people who are found therein shall become tributary to you, and shall serve you.

If it will make no peace with you, but will make war against you, then you shall besiege it:

You shall not seek their peace nor their prosperity all your days forever.

and you shall sacrifice peace offerings, and shall eat there; and you shall rejoice before Yahweh your God.

and it happen, when he hears the words of this curse, that he bless himself in his heart, saying, "I shall have peace, though I walk in the stubbornness of my heart, to destroy the moist with the dry."
