john 19:36 For these things were done, that the scripture should be fulfilled, A bone of him shall not be broken. - Free Bible Online

      36. that the scripture should be fulfilled, A bone of him shall not be broken--The reference is to the paschal lamb, as to which this ordinance was stringent (Ex 12:46; Nu 9:12. Compare 1Co 5:7). But though we are to see here the fulfilment of a very definite typical ordinance, we shall, on searching deeper, see in it a remarkable divine interposition to protect the sacred body of Christ from the last indignity after He had finished the work given Him to do. Every imaginable indignity had been permitted before that, up to the moment of His death. But no sooner is that over than an Unseen hand is found to have provided against the clubs of the rude soldiers coming in contact with that temple of the Godhead. Very different from such violence was that spear-thrust, for which not only doubting Thomas would thank the soldier, but intelligent believers in every age, to whom the certainty of their Lord's death and resurrection is the life of their whole Christianity.
