"And He left them, and departed." How sad for Him; how awful for them! Had there been in their hearts one single aspiration for the true and good, He would not have left them so. Where are these Pharisees and Sadducees now? What do they now think of the work of that day?
"He left them, and again entering into the boat departed to the other side" (Mark viii. 13). Did He ever cross the lake again? If He did, there is no record of it. He passed in sight of it in that sorrowful southward journey to Jerusalem which He must presently commence; and He will visit the same shore again after His resurrection to cheer the apostles at their toil; but this seems to have been the last crossing. What a sad one it must have been!--after a beginning so bright that it was heralded as daybreak on Gennesaret's shore, after all His self-denying toil, after all the words of wisdom He has spoken and the deeds of mercy He has done upon these shores, to leave them, as He does now, rejected and despised, an outcast, to all outward appearance a failure. No wonder He is silent in that crossing of the lake; no wonder He is lost in saddest thought, turning over and over in His mind the signs of the times forced so painfully on His attention!
The disciples with Him in the boat had no share in these sad thoughts. Their minds, as it would seem, were occupied for the most part with the mistake they had made in provisioning the boat. Accordingly, when at last He broke silence, He found them quite out of touch with Him. He had been thinking of the sad unbelief of these Pharisees and Sadducees, and of the awful danger of allowing the spirit which was in them to dominate the life; hence the solemn caution: "Take heed, and beware of the leaven of the Pharisees and of the Sadducees." The disciples meantime had been counting their loaves, or rather, looking sadly on the one loaf which, on searching their baskets, they found to be all they had; and when the word _leaven_ caught their ear, coupled with a caution as to a particular kind of it, they said one to another, "It is because we have taken no bread!" Another cause of sadness to the Master. He had been mourning over the blindness of Pharisees and Sadducees; He must now mourn over the blindness of His own disciples; and not blindness only, but also forgetfulness of a thrice-taught lesson: for why should the mere supply of bread be any cause of anxiety to them, after what they had seen once and again in these very regions to which they were going?
But these hearts were not shut against Him; theirs was not the blindness of those that will not see; accordingly, the result is very different. He did not leave them and depart; nor, on the other hand, did He explain in so many words what He meant. It was far better that they should find out for themselves. The riddles of nature and of life are not furnished with keys. They must be discerned by thoughtful attention; so, instead of providing them a key to His little parable, He puts them in the way of finding it for themselves by asking them a series of questions which convinced them of their thoughtlessness and faithlessness, and led them to recognise His true meaning (vv. 8-12).
