'Beneficial' in the Bible
The young lions lack food and suffer hunger, but they who seek (inquire of and require) the Lord [by right of their need and on the authority of His Word], none of them shall lack any beneficial thing.
Salt is good (beneficial), but if salt has lost its saltness, how will you restore [the saltness to] it? Have salt within yourselves, and be at peace and live in harmony with one another.
Let no foul or polluting language, nor evil word nor unwholesome or worthless talk [ever] come out of your mouth, but only such [speech] as is good and beneficial to the spiritual progress of others, as is fitting to the need and the occasion, that it may be a blessing and give grace (God's favor) to those who hear it.
Who gave Himself on our behalf that He might redeem us (purchase our freedom) from all iniquity and purify for Himself a people [to be peculiarly His own, people who are] eager and enthusiastic about [living a life that is good and filled with] beneficial deeds.
