James 3:10-12

Verse 10. Out of the same mouth proceedeth blessing and cursing. The meaning here may be, either that out of the mouth of man two such opposite things proceed, not referring to the same individual, but to different persons; or, out of the mouth of the same individual. Both of these are true; and both are equally incongruous and wrong. No organ should be devoted to uses so unlike, and the mouth should be employed in giving utterance only to that which is just, benevolent, and good. It is true, however, that the mouth is devoted to these opposite employments; and that while one part of the race employ it purposes of praise, the other employ it in uttering maledictions. It is also true of many individuals that at one time they praise their Maker, and then, with the sane organ, calumniate, and slander, and revile their fellow-men. After an act of solemn devotion in the house of God, the professed worshipper goes forth with the feelings of malice in his heart, and the language of slander, detraction, or even blasphemy on his lips.

My brethren, these things ought not so to be. They are as incongruous as it would be for the same fountain to send forth both salt water and fresh; or for the same tree to bear different kinds of fruit.
Verse 11. Doth a fountain send forth at the same place. Marg., hole. The greek word means opening, fissure, such as there is in the earth, or in rocks from which a fountain gushes.

Sweet water and bitter. Fresh water and salt, Jas 3:12. Such things do not occur in the works of nature, and they should not be found in man.

(+) "place" or, "hole"
Verse 12. Can the fig-tree, my brethren, bear olive berries? Such a thing is impossible in nature, and equally absurd in morals. A fig-tree bears only figs; and so the tongue ought to give utterance only to one class of sentiments and emotions. These illustrations are very striking, and show the absurdity of that which the apostle reproves. At the same time, they accomplish the main purpose which he had in view, to repress the desire of becoming public teachers without suitable qualifications. They show the power of the tongue; they show what a dangerous power it is for a man to wield who has not the proper qualifications; they show that no one should put himself in the position where he may wield this power without such a degree of tried prudence, wisdom, discretion, and piety, that there shall be a moral certainty that he will use it aright.

(a) "Can the fig-tree...bear olive berries" Mt 7:16
