'Gain' in the Bible

for [the] wicked boasts about the desire of his {heart}, and [the] one greedy for gain curses [and] treats Yahweh with contempt.

"What gain [is there] in my {death}, in my going down into [the] pit? Will [the] dust praise you? Will it tell of your faithfulness?

So teach [us] to number our days that we may gain a heart of wisdom.

Incline my heart to your testimonies, and not to [dishonest] gain.

Direct my steps in your word, and do not let any iniquity gain power over me.
