Matthew Henry and continuators on Proverbs 17:19

19 He loveth transgression that loveth strife: and he that exalteth his gate seeketh destruction.

Note, 1. Those that are quarrelsome involve themselves in a great deal of guilt: He that loves strife, that in his worldly business loves to go to law, in religion loves controversies, and in common conversation loves to thwart and fall out, that is never well but when he is in the fire, he loves transgression; for a great deal of sin attends that sin, and the way of it is down-hill. He pretends to stand up for truth, and for his honour and right, but really he loves sin, which God hates. 2. Those that are ambitious and aspiring expose themselves to a great deal of trouble, such as often ends in their ruin: He that exalts his gate, builds a stately house, at least a fine frontispiece, that he may overtop and outshine his neighbours, seeks his own destruction and takes a deal of pains to ruin himself; he makes his gate so large that his house and estate go out at it.
