Matthew Henry and continuators on Proverbs 18:17

17 He that is first in his own cause seemeth just; but his neighbour cometh and searcheth him.

This shows that one tale is good till another is told. 1. He that speaks first will be sure to tell a straight story, and relate that only which makes for him, and put the best colour he can upon it, so that his cause shall appear good, whether it really be so or no. 2. The plaintiff having done his evidence, it is fit that the defendant should be heard, should have leave to confront the witnesses and cross-examine them, and show the falsehood and fallacy of what has been alleged, which perhaps may make the matter appear quite otherwise than it did. We must therefore remember that we have two ears, to hear both sides before we give judgment.
