'Gain' in the Bible

Therefore the Lord God of Hosts,the Mighty One of Israel, declares:“Ah, I will gain satisfaction from My foes;I will take revenge against My enemies.

Those who are confused will gain understanding,and those who grumble will accept instruction.

The reckless mind will gain knowledge,and the stammering tongue will speak clearly and fluently.

The one who lives righteouslyand speaks rightly,who refuses gain from extortion,whose hand never takes a bribe,who stops his ears from listening to murderous plotsand shuts his eyes to avoid endorsing evil—

These dogs have fierce appetites;they never have enough.And they are shepherdswho have no discernment;all of them turn to their own way,every last one for his own gain.
