'Gain' in the Bible

He who walks [in] righteousness and speaks uprightness, who rejects [the] gain of extortion, who {refuses} bribe, who stops up his ears from hearing {bloodshed} and shuts his eyes from seeing evil.

And the dogs {have a greedy appetite}; they {are never satisfied}. And they are [the] shepherds! They do not have understanding. They all turn to their [own] way, each one for his [own] gain, {every one of them}.

I was angry because of his sin of gain, and I struck him; I hid and I was angry, but he walked apostate, in the ways of his heart.
