John Gill Commentary Proverbs 25:8

"Go not forth hastily to strive, Lest [thou know not] what to do in the end thereof, When thy neighbor hath put thee to shame." — Proverbs 25:8 (ASV)

Go not forth hastily to strive To go to law with a neighbour; think well of it beforehand; consider the nature of the cause, whether right or wrong; or whether it is a matter of such moment as to go to law about; whether it will not be deemed a frivolous and vexatious suit; whether able to bear the expenses of it, and what may probably be the success of it;

lest [you know not] what to do in the end thereof; for a livelihood, having spent all your substance in the lawsuit, and so reduced to poverty as not to know how to live, or how and where to show your face, through the disgrace that shall fall upon you by losing the cause;

when that neighbour has put you to shame; in open court, and proved himself to be in the right, and that you are in the wrong; himself an honest man, and you a litigious person.
