My son, if sinful men entice you, do not give in to them.
If they say, “Come along with us; let’s lie in wait for innocent blood, let’s ambush some harmless soul;

Maybe I haven't been reading enough commentaries, but it only just occurred to me the other day that this is explicitly addressed to "my son." A king isn't likely to join a common bandit gang--he's more likely to join other kings in ganging up on a land that seems worth conquering. OK, so if I treat this as a parable of wider application than just street gangs to whom else does it apply? Somebody with some power (more of us than we like to think, but not all).
