SEV Biblia, Chapter 9:50
Buena es la sal; mas si la sal fuere desabrida, ¿con qu la adobaris? Tened en vosotros mismos sal; y tened paz los unos con los otros.
Clarke's Bible Commentary - Mark 9:50
Verse 50. If the salt have lost his saltness] See on Matt. v. 13. Have salt in yourselves] See that ye have at all times the preserving principle of Divine grace in your hearts, and give that proof of it which will satisfy your own minds, and convince or silence the world: live in brotherly kindness and peace with each other: thus shall all men see that you are free from ambition, (see ver. 34,) and that you are my disciples indeed. That it is possible for the salt to lose its savour, and yet retain its appearance in the most perfect manner, see proved on the note on Matthew v. 13.
John Gill's Bible Commentary
Ver. 50. Salt is good , etc..] To make meat savoury, and keep flesh from corrupting; and so is the grace of God, to season men's hearts, make their discourse savoury, and preserve them from the corruption of sin: and so men made partakers of the grace of God; they are good and useful to others, both by their words and actions, and especially ministers of the Gospel, who are the salt of the earth, (see Gill on Matthew 5:13); and here Christ may chiefly intend his apostles: but if the salt hath lost its saltness, wherewith will ye season it ? there is no recovering it, it becomes good for nothing; (see Gill on Matthew 5:13); have salt in yourselves ; the doctrine of grace, and word of Christ, prudence in talk and conversation, and holiness of heart and life, so as to behave wisely towards them that are without; and have peace one with another ; which the God of peace calls unto, the Gospel of peace requires, and the grace of God teaches. Salt is an emblem of firm union, concord, and agreement: hence the covenant of peace is called a covenant of salt, ( Numbers 18:19), compared with ( Numbers 25:12). This exhortation, very appropriately follows upon the making mention of salt in different senses; especially, this exhortation was the more necessary to the disciples at this time, since they had been very lately warmly disputing the point among themselves, who should be greatest in the kingdom of the Messiah; and which had occasioned this discourse of Christ's.
Matthew Henry Commentary
Verses 41-50 - It is repeatedly said of the wicked, Their worm dieth not, as well as The fire is never quenched. Doubtless, remorse of conscience and kee self-reflection are this never-dying worm. Surely it is beyond compar better to undergo all possible pain, hardship, and self-denial here and to be happy for ever hereafter, than to enjoy all kinds of worldl pleasure for a season, and to be miserable for ever. Like the sacrifices, we must be salted with salt; our corrupt affections must be subdued and mortified by the Holy Spirit. Those that have the salt of grace, must show they have a living principle of grace in their hearts which works out corrupt dispositions in the soul that would offend God or our own consciences __________________________________________________________________

Vincent's NT Word Studies
50. Have lost its saltness (analon genhtai). Lit., may have become saltless. Compare on Matt. v. 13.Will ye season (artusete). Lit., will ye restore. Compare Col. iv. 5.
Robertson's NT Word Studies
9:50 {Have salt in yourselves} (ecete en heautois hala). Jesus had once called them the salt of the earth (#Mt 5:13) and had warned them against losing the saltness of the salt. If it is analon, nothing can {season} (artuw) it and it is of no use to season anything else. It is like an exploded shell, a burnt-out crater, a spent force. this is a warning for all Christians.
