'Stops' in the Bible

Their poison is like the poison of a snake; like a deaf cobra that stops its ear,

Whoever stops his ears at the cry of the poor, he will also cry out, but shall not be heard.

He who walks righteously, and speaks blamelessly; He who despises the gain of oppressions, who gestures with his hands, refusing to take a bribe, who stops his ears from hearing of blood, and shuts his eyes from looking at evil --

They are all adulterers. They are burning like an oven that the baker stops stirring, from the kneading of the dough, until it is leavened.
