Proverbs 23:10 Meaning and Commentary

Proverbs 22:10

Remove not the old landmark (See Gill on Proverbs 22:28); and enter not into the fields of the fatherless;
to carry off the increase of them, to reap their wheat, or mow their grass, or turn in cattle to eat it; or to encroach upon them, take in any part of them, or join the whole to their own; for if there is a woe to them that lay field to field, much more to them that enter into and take the fields of the fatherless, and join them to their own, ( Isaiah 5:8 ) .

9 Don't speak in the ears of a fool, for he will only despise the common sense in your words.
10 Don't move the ancient boundary stone or encroach on the land of the fatherless;
