When I first heard this lyric sung by Sarah Masen on her 2007 ep, A History of Light and Shadow, I laughed out loud. If you don't know this singer/songwriter (and you should), you may not know she sometimes sings a thin, almost girlish voice, airy and innocent. The voice helped add to my laughter. It was a laugh of surprise as much of humor. This sweet voice recounting the Messiah's triumphant entry into Jerusualm and then simply deciding, "let's kill him."
Of course, it's a sad thing, too. Someone comes preaching good news to the poor and release to the captives, and we shout out "Hosanna!" because we want our bit of salvation, too. Then, we see who he means. He means not only (or necessarily!) us, but also those people over there. You know the ones. Those people.
And when you get right down to it, isn't he kind of sickening? Putting on this show of humility, riding a donkey, acting all lowly? C'mon, you're our King. This is amusing and we'll praise you for it, but now, let's get down to business. When are you going to overthrow our oppressors? When do we get to see them get theirs?
What? We don't? You're not gonna? This royally pisses me off.
Let's kill him.
It's funny because it's true. That's how we are.
It's sad for the same reason.
