'Gain' in the Bible

For her profit is better than the profit of silverAnd her gain better than fine gold.

Hear, O sons, the instruction of a father,And give attention that you may gain understanding,

Strike a scoffer and the naive may become shrewd,But reprove one who has understanding and he will gain knowledge.

Do not weary yourself to gain wealth,Cease from your consideration of it.

A leader who is a great oppressor lacks understanding,But he who hates unjust gain will prolong his days.

The heart of her husband trusts in her,And he will have no lack of gain.

She senses that her gain is good;Her lamp does not go out at night.
