Matthew Henry on Judges 12

The Ephraimites had the same quarrel with Jephthah as with Gideon. Pride was at the bottom of the quarrel; only by that comes contention. It is ill to fasten names of reproach upon persons or countries, as is common, especially upon those under outward disadvantages. It often occasions quarrels that prove of ill consequence, as it did here. No contentions are so bitter as those between brethren or rivals for honour. What need we have to watch and pray against evil tempers! May the Lord incline all his people to follow after things which make for peace!

We have here a short account of three more of the judges of Israel. The happiest life of individuals, and the happiest state of society, is that which affords the fewest remarkable events. To live in credit and quiet, to be peacefully useful to those around us, to possess a clear conscience; but, above all, and without which nothing can avail, to enjoy communion with God our Saviour while we live, and to die at peace with God and man, form the substance of all that a wise man can desire.
