He who walks righteously and speaks uprightly, who despises the gain of oppressions, who shakes his hands, lest they hold a bribe, who stops his ears from hearing of bloodshed and shuts his eyes from looking on evil, he will dwell on the heights; his place of defense will be the fortresses of rocks; his bread will be given him; his water will be sure.
Isaiah 33:15-16 (ESV)
