When David heard that Absalom was slain
He went up into his chamber over the gate and wept,
and thus he said: my son, my son, O Absalom my son,
would God I had died for thee!
There's something about this particular text that always feels incredibly "Passion-time-y" to me, because I always imagine God the Father using David's words with reference to Jesus. (Like all analogies about God, it breaks down eventually. Immediately, even. But I find it incredibly powerful and comforting, all the same.)
