Does the verse simply mean that the wake was still continuing by custom so Jesus joined with them for some kind of "weeping and wailing" tradition- before the amazing resurrection of the dead man who was rotting? Were the tears because the Father had made him wait do nothing for those 4 days? Were they tears for His own grief to come?
ESV - 35 Jesus wept.
