Surely the churning of milk bringeth forth butter
Or the pressing of it. This is a thing well known and certain, that of milk, when pressed out of the udder, and put into a churn, and there is shook together, by a constant violent agitation or motion, called churning, butter is produced; and cheese is sometimes called pressed milk F25, and is pressed with the runnet, and by the hand also F26; and the wringing of the nose bringeth forth blood:
a too violent compression of it, or forcible blowing of it, in order to purge it from any impurity in it; instead of doing which it may break the tender skin, and bring forth blood, which may be of bad consequence; so the forcing of wrath bringeth forth strife;
irritating the passions of men, and provoking them by scurrilous and reproachful words to wrath and anger, produce contentions, feuds, and lawsuits, which are not soon and easily ended; and therefore such a conduct should be carefully avoided. The same word is used in the three clauses, and signifies pressing, squeezing, forcing.
