Genesis 49:27 - Matthew Poole's English Annotations on the Holy Bible

He notes the warlike and fierce disposition and carriage of that tribe. Instances whereof we have Judges 3:15, Judges 19:1-20:48 1 Samuel 13:1-15:35. This may be understood, either of the same wolf, which in the morning, being more hungry and greedy, devours his prey alone; but in the evening, being in some measure satisfied, is content that his brethren should share with him. Or rather of several sorts of wolves, whereof some hunt and devour alone, others hunt in couples or troops, and those divide the prey among themselves. He mentions both morning and evening, because these are the two seasons when the wolves prey, and to note that this would be Benjamin's carriage both in the first and last times of that tribe, as indeed it was.
