Matthew Poole and continuators on Genesis 49:27

27 Benjamin shall ravine as a wolf : in the morning he shall devour the prey: and at night he shall divide the spoil .

He notes the warlike and fierce disposition and carriage of that Tribe. Instances whereof we have, Judg. 3. 15. and 19. and 20. 1 Sam. 12. and 14. and 15.

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 troups, and these 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 Benjamins carriage both in the first and last times of that Tribe, as indeed it was.
