'Peace' in the Bible

[Then] sent the king an answer to Rehum the chancellor, and to Shimshai the scribe, and to the rest of their companions who dwell in Samaria, and in the rest [of the country] beyond the River: Peace, and so forth.

they sent a letter to him, in which was written thus: To Darius the king, all peace.

Now therefore don't give your daughters to their sons, neither take their daughters to your sons, nor seek their peace or their prosperity forever; that you may be strong, and eat the good of the land, and leave it for an inheritance to your children forever.'
