'Beneficial' in the Bible

The young lions lack [food] and grow hungry,But they who seek the Lord will not lack any good thing.

where their worm [that feeds on the dead] does not die, and the fire is not put out.

Do not let unwholesome [foul, profane, worthless, vulgar] words ever come out of your mouth, but only such speech as is good for building up others, according to the need and the occasion, so that it will be a blessing to those who hear [you speak].

who [willingly] gave Himself [to be crucified] on our behalf to redeem us and purchase our freedom from all wickedness, and to purify for Himself a chosen and very special people to be His own possession, who are enthusiastic for doing what is good.
